Bloated stomach.
At 4 weeks pregnant, you might experience a bit of bloating and cramping particularly in your abdomen, as your uterine lining is getting a bit thicker, and the swelling means your womb is taking up more space than usual.
How soon can you tell you're pregnant with twins? Your doctor won't be able to tell for sure until your first trimester ultrasound, which is usually done between 6 and 9 weeks of pregnancy but can be done any time before week 14.
Your Baby at Week 4
You normally don't have your first ultrasound until at least week 6, but you might be able to spot the gestational sac as early as halfway through week 4 — and if you're having twins, you'll likely see two of them! Before the placenta forms, you develop a yolk sac, which can be visible next week.
In a twin pregnancy, there are elevated levels of hCG, making it possible to have a very early positive result. However, home pregnancy tests won't confirm if twins are present, only the presence of hCG. It takes around 2 weeks after conception for hCG to be detected in a hCG pregnancy test.
Any positive line, no matter how faint, means your result is pregnant. Levels of hCG in your body will increase over the course of your pregnancy. If you test early, your hCG levels may be still be low and you'll see a faint positive line.
By the time you're four weeks pregnant, your twins will each be about the size of a poppy seed. Their hearts will begin to beat in the next week, pumping blood throughout their tiny bodies. Even at this early stage, vital parts of your twins' nervous systems are already developing.
Week 4 of pregnancy
For example, a fertilised egg may have implanted in your womb just 2 weeks ago, but if the first day of your last period was 4 weeks ago, this means you're officially four weeks pregnant! Pregnancy normally lasts from 37 weeks to 42 weeks from the first day of your last period.
It is very common to get backache or back pain during pregnancy, especially in the early stages. During pregnancy, the ligaments in your body naturally become softer and stretch to prepare you for labour. This can put a strain on the joints of your lower back and pelvis, which can cause back pain.
At 5 weeks pregnant, your belly may look unchanged—or you may be a bit bloated or feel like you've already gained a pound. Heck, you might feel so sick that you can't eat and worry you could have lost a pound. All those scenarios are considered perfectly normal and totally okay!
At 5 weeks pregnant, your belly may be starting to look slightly different – perhaps like you had a big lunch. For some women, abdominal bloating due to hormonal changes is an early sign of pregnancy.
What's happening in my body? You probably don't look pregnant yet. If it's your first pregnancy you might not start showing until at least week 12. However, if this isn't your first baby, you may start showing sooner, as the muscles in your uterus (womb) and belly may have been stretched from your last pregnancy.
Older women and women who have been pregnant before can show as early as the first trimester. Also, women who don't have strong core muscles may show earlier because their muscles are relaxed. Their stomach adapts more easily to looking pregnant.
When you can do a pregnancy test. You can carry out most pregnancy tests from the first day of a missed period. If you don't know when your next period is due, do the test at least 21 days after you last had unprotected sex. Some very sensitive pregnancy tests can be used even before you miss a period.
Most home pregnancy tests detect pregnancy about two weeks after conception, so you might want to jump to week 4.
“Early on in your pregnancy, it's natural to feel some mild cramping in your lower abdomen at infrequent times as your body prepares for your growing baby,” Dr. Nalla said. As your belly grows, so does your uterus. This may cause you to feel some slight pulling, tugging or stretching similar to period cramps.
Pregnant women carrying girls have a greater chance of experiencing nausea and fatigue, according to the results of a study from the USA's Ohio State University Wexner Medical Center.
In which week of pregnancy will an ultrasound show twins? Your healthcare provider will be able to determine if you're having twins at your first ultrasound, which often takes place at about 12 weeks.
Boys' and girls' genitals develop along the same path with no outward sign of gender until about nine weeks. It's at that point that the genital tubercle begins to develop into a penis or clitoris. However, it's not until 14 or 15 weeks that you can clearly begin to see the differentiated genitalia.
An immediate dark positive result could mean that there's a high concentration of hCG in your urine, and the test is showing an immediate dark result due to the hormone level. One thing to note is that all home pregnancy tests are different and may detect hCG at different levels.
If the result is positive, you can try to schedule an appointment with a health care provider, although many health care providers wait to see you until you are 8 to 12 weeks pregnant. If your test is negative and your period is late, then you should wait a week before testing again.
If you see any line on your COVID test, err on the side of caution and take precautions to avoid spreading the virus to others. While a dark line that shows up quickly is a sign that there's more virus in your body, even a faint line can be positive (and may turn darker if you test again in the coming days).
