I had a medical abortion about three weeks ago. I took a pregnancy test about 4 days ago and it came out negative meaning that everything went how it should have. Last week me and my boyfriend 'had sex' three times. I wouldn't really call it having sex as my boyfriend only went inside of me for only about a minute two times of those three. The third time we used a condom and the ejaculation still took place outside of my vagina. Today, about a week after our first intercourse since my abortion, my nipples hurt a little when touched. My question is, what are the chances of me being pregnant again? Thank you for answers.
