I'm 17, 5'4 and weigh 113 lbs I've been on the mini pill since 5/29 I took the pill 4 hours after my usual time on 6/8 and had sex the next day on 6/9 (he came inside me, no other protection was used). My period was three days late and came on 6/22 it was extremely light for about two days and I've been spotting until today, 6/25. I'm really naesous. I took a pregnancy test on 6/23 and it came out negative.. Could I still be pregnant or should I not even worry?
