Period like symptoms lead to bfp??

Has anyone ever felt like they were having their period but it lead to a bfp? I’ve been spotting super light for 6 days now and have had sore breasts/period like cramps but have not gotten my period. My cycles are usually a normal 28-30 day cycle but I started spotting on cd21 and it hasn’t stopped but I haven’t gotten a period either... I got a super vfl yesterday and I’m going to test again tomorrow but was wondering if anyone has any insight
