Pregnancy IS a possibility. My period is officially a week late as of today. I have been having period l-like cramps for the past week. Took a test on Saturday, negative. Last night I thought my period was starting, dark brown discharge. So I put in a tampon, took it out this morning. Only the very corner had dark brown blood on it, almost like I was ending my period. This has never happened before. I never “spot” so I don’t know what’s happening. Also, my boobs have been EXTREMELY sore, which rarely happens.
