On Monday, 5 days ago, according to a 28 day cycle, my period was supposed to start. My period is now 5 days days late. I also had protected (condom) sex on Monday.
I am currently on birth control pills (Sprintec). However, for the past 3 months I have been off schedule. I forgot to take the pill the same time everyday or sometimes I accidentally skip a day or two. Last month, I was so off schedule that I accidentally skipped the inactive pills and continued through this month with active pills. Today, I'm still on the active pills.
Yesterday, I took a home pregnancy test (First Response) in the afternoon. It came out negative. However, I'm still worried about the possibility of being pregnant. I have been experiencing cramps and pain in left abdomen. No nausea or sickness.
Could I be pregnant?
