Confused 🙊

Diana

First start from 27 until 31 dec me and my bf had sex use pull out metode and sometimes use condom. then at new year night we had sex without condom and he came inside. then after like 59 hours later (3 january) i drank emergency contraception pills, i was sweaty a lot at night after i drink it. So, the problem is i started to got some cramps start from 10 january until now and my nippl is more sensitive than usual also back pain. and today, my period is already 3 days late. i'm worried so i did a pregnancy test but it's negative. Did you girls ever got in this situation or know about this?? thanks 🙌 ❤
