In addition to Judaism and Christianity, Islam also forbids men to have vaginal sexual intercourse with their wives during menstruation (Surah al-Baqarah 2:222).
Things you should avoid
“Consumption of excess salt causes water retention that leads to bloating during your period,” said Dr Patil. In fact, also avoid spicy food since it can upset your stomach and cause acid refluxes. “Avoid drinks like coffee, energy drinks etc as they can cause headaches and constipation.
Cultural norms and religious taboos on menstruation are often compounded by traditional associations with evil spirits, shame and embarrassment surrounding sexual reproduction. [2] In some cultures, women bury their cloths used during menstruation to prevent them being used by evil spirits.
During menstruation the impure blood from the body flows out, which needs better hygiene to avoid infections and ailments. Earlier, women used cloth to manage hygiene during those days, but over a period of time there have been many ways to maintain a healthy hygiene and reduce chances of infections.
II. Vaginal sexual intercourse with a menstruating woman could lead to an increase in the flow of menstrual blood (18), because the veins of the uterus are congested and prone to rupture, and thus are damaged easily. Some women actually notice that their period stops one or two days after sexual intercourse.
Women are supposed to maintain proper hygiene and should not perform prayer. They do not have to make up the prayers they missed during menstruation. When the menstruating period is over, women have to perform ritual purification (ghusl).
Contrary to that belief, the blood you menstruate is just as “clean” as the venous blood that comes from every other part of the body and it's harmless as long as you don't have any bloodborne diseases (pathogens aren't picky when it comes to manifesting in bodily fluids).

Praise and salutations to our beloved Prophet Muhammad PBUH, his family, companions, and all those who follow his footsteps until the Final day. Thus, in our opinion, cutting hair and clipping nails during menstruation or major hadas is not prohibited.
He (the Holy Prophet) said: She should take water and cleanse herself well or complete the ablution and then (pour water) on her head and rub it till it reaches the roots of the hair (of her) head and then pour water on her.
Sperm can survive in a woman's reproductive system for up to 5 days whether the woman is menstruating or not. Thus, even if a woman has sex during her period, sperm from ejaculation may remain inside her reproductive system and may fertilize the egg if ovulation occurs.
Most girls use pads when they first get their period. Pads are made of cotton and come in lots of different sizes and shapes. They have sticky strips that attach to the underwear. Many girls find tampons more convenient than pads, especially when playing sports or swimming.
More estrogen is made early in the cycle and it peaks just before mid-cycle. This causes the breast ducts to grow in size. The progesterone level peaks near the 21st day (in a 28-day cycle). This causes growth of the breast lobules (milk glands).
If it's not really affecting your relationship, then it's entirely up to you whether you want to tell him. If you want to keep it private, that's totally fine. If you want to be up front about it, then go for it.
