My periods have never been this light but this month there is something strange. I had my last period last month on the 14th-18th. I am sexually active and I end up having sex on the 20th (2 days after my period). He wore a condom but when he pulled out I notice that the condom had broke. He said he didn't come but I am also aware that some pre-come can contain sperm. I waited to take a home pregnancy test so that I can see how my cycle would flow or would it even come at all. It came today like @1-2 this morning. I checked my pad & there was a brownish-red blood in my pad which was abnormal because my cycle is always heavy on the first day. I was planning to take a HPT once my cycle go off or just schedule a docs appointment but should I be worried that I could be pregnant?
