I have been suffering from endometriosis and on the beginning of this month that's 4th I had sex and got my periods on 6th could this have caused infertility
Yes, endo might be one of the reason why a woman can't get pregnant. I recommend seeing a doc to discuss yr issues. In case of mild or mild to moderate endo, the treatment means limiting the symptoms of the disease. In case of more problematic endo, a woman might be recommended undergoing ivf. I come across many posts of ladies suffering from endometriosis, who have undergone ivf in top clinics (Invicta, Zlin, Prague) and got pregnant.
