Can I be pregnant if I had sex on the first day of my period?

The risk of getting pregnant during intercourse is low because sperm must be in the vagina and not in the anus to fertilize the egg. The only way for this to happen is for sperm to leak out of the anus and get into the vagina. This is unlikely. The condition for fertilization is also the presence of an egg in the genital tract, which means that a woman at the time of intercourse must be at fertile time in order for pregnancy to occur. The first day of the cycle (the first day of menstruation) with normal, regular cycles is generally not fertile. In the case described, the risk of pregnancy seems low, but just four days after sexual activity, it is impossible to assess whether it has occurred. A temperature of 36.7 is normal. An unusually short period and additional spotting after menstruation is a topic for consultation with a gynecologist - it is difficult to assess without an interview and examination what could have been caused by it.
