I had sex w my ex boyfriend The beginning of April up until April 23rd. April 23rd he came inside of me. We broke up, on April 29th I had unprotected sex w a friend( he didn’t not finish, although I know there’s a chance of pre ***) 4 days later on May 3rd I took a pregnancy test and it was positive, very faint but positive. Using the conception calculator basing it off of my LMP the best days for sex were April 18-23rd. Ovulated the 23rd but I am still very worried. Can you get a positive pregnancy test 4 days after sex? The line was very faint. HCG levels are 183. 4 weeks according to the conception calculator.
