There's no evidence to show that any sleeping position is better than any other for embryo implantation. The embryo is transferred when your womb is ready, when the lining is soft and thick and ideal for an embryo to implant. You can lie however you like – just get comfy.
No particular sex position has been proven to improve the odds of pregnancy. What may help is to put sperm as close to the cervix -- the canal that connects the vagina and the womb -- as possible.
It's recommended that you avoid strenuous physical activities like heavy weight-lifting or high-impact cardio during your two-week wait as it could lead to uterine contractions and affect the implantation process. After the first few days of our waiting period, you can do some light exercising like walking or swimming.
The best diet to aid implantation is the same diet you should be eating throughout your treatment and pregnancy: nutritionally balanced with lots of protein, fiber, and vegetables. Avoid foods like high-mercury fish and soft cheeses, and check with your doctor about any vitamins or supplements you should be taking.
Screen for underlying health conditions – Sometimes underlying health conditions can prevent an embryo from implanting. These can include uterine problems, hormonal issues, thyroid problems, diabetes, and many others. Even a prior infection can cause implantation troubles.
What can cause implantation to fail? Unfortunately, various conditions can hamper the proper implantation of a blastocyst. In some cases, genetic disorders in the developing embryo disrupt the trypsin signal and cause a stress reaction that forces the uterus to reject the blastocyst.
The peer-reviewed study, published in Human Reproduction Update, importantly found that prolonged bed rest (for more than 20 minutes) immediately after embryo transfer was associated with a 15% reduction in the chances of clinical pregnancy.
Your implantation of embryo is not going to be affected by a little bit of bending or sitting or inserting vaginal tablet.
During the two-week wait, it's better to err on the side of caution. Avoid having a drink, smoking, or any other activity that could be harmful to a brand new pregnancy. It's fine to continue exercising if you already have a workout routine, but now might not be the time to take up a new, intense form of exercise.
For an embryo to successfully implant in the uterus, the endometrium (the tissue that grows on the internal lining of the uterus) must undergo biological changes. In preparation for a healthy embryo, the endometrium thickens and becomes responsive to potential implantation by the embryo.
However, the science shows us that implantation most commonly occurs on days 8, 9, and 10 past ovulation. Since it takes a few days for hCG to show up in your urine, the earliest you could get a positive pregnancy test if your embryo implanted on day 8 past ovulation would be day 10.
Progesterone is what stabilizes the uterine lining and makes it “sticky” enough for an embryo to attach. Without enough progesterone, it can be more difficult for an embryo to successfully implant. Progesterone stabilizes the uterine lining and makes it “sticky” enough for an embryo to attach.
This means the implantation takes place about 7 to 8 days after fertilization of the egg. The time required for implantation in both the cases, normal pregnancy and pregnancy through IVF, is more or less the same.
Without enough water, the cervical mucus that balances vaginal pH also becomes too acidic, harming the sperm. Implantation – Water is necessary for cell division and metabolism. The cells of the uterine wall must be healthy for the embryo to implant.
Current studies show that maternal caffeine exposure not only severely disrupts embryo implantation but also disrupts ongoing midterm fetal growth and development, resulting in pregnancy loss, low birth weight, and impaired brain development in offspring on postnatal day 6 (P6) [35–38,55].
Don't drink coffee or alcohol
Try to avoid alcohol entirely and limit your coffee intake to at least below 200 milligrams a day during the two-week period for optimal results.
It is within this time frame that an embryo has to “attach” to the uterine wall before it can fully implant, which may take several days. Therefore, for the first one to two days, stay home and chill out. Avoid vigorous activities such as heavy lifting, bending or exercise.
Women who usually slept supine at the time of conception and implantation were significantly more likely to have a high or fundal placental location compared with those who usually slept in the prone position (p = 0.041).
Does holding up your legs and hips after sex increase the odds of getting pregnant? No, your position after sex doesn't matter either. There's no scientific evidence that elevating your hips or lying down after sex helps sperm reach the cervix (5).
