I had an unprotected intercourse with my partner. So basically we tried the pullover method. Where he pulled it out whenever he feels like he's going to cum so that it won't drop into the vagina. We had 4 rounds with the protection and rest without it. Believing that there is not much semen till then and if any he'll pull it out. I've taken an I pill under the timeline of 72 hours. But I am now feeling a bit of pain in my stomach. So just wanted a consultation on this if it is normal or not.
