Am I pregnant?

I started taking birth control and was inconsistent in taking in when I first started. My partner and I were actively having unprotected sex with insemination. The day after we had sex I spotted super light pink. I’ve never had that happen before. Second day same spotting. Then no spotting at all. I kept taking birth control pills and we remained sexually active with insemination.

I checked glow and it showed we had sex during my estimated ovulation timeframe. The week of my period I spotted brown very light spotting for 3 days. It stopped and I still haven’t gotten my period (3 days late right now). I’ve taken 3 pregnancy tests while I was spotting the 3 days. All were negative. I’ve been bloated like nobody’s business lol somewhat nauseous off and on not too terrible. Some mild hot flashes. I plan to test again in the next day or so. But this is driving me crazy. I finished my birth control pack and haven’t started the new one for fear of being pregnant and not wanting to hurt the pregnancy if so. But I’m testing negative and all research says I had insemination bleeding. Thoughts ladies?
