A question of an intimate nature, before pregnancy we had interrupted sexual intercourse with my husband for 4 years, everything was great ?? But now after I gave birth, the body works differently, did it wake up, is it dangerous to engage in PPA? I don't want to put a coil, I think about pills ? Has anyone had such experience? You can't get pregnant, I had a miscarriage, I plan only after 3-4 years.
