Opinions?

Ok ladies I need help. As you can see my period is super late. I took pregnancy tests from the dollar store in the morning on both the 8th and the 9th both with BFN. On the 10 me and DH had sex and their was slight blood spotting on him after but no more blood after or following and usually I’ve only bled from sex during previous pregnancy’s. I’ve had sore boobs and migraines and cramps in my belly and my back. I don’t *feel* pregnant but I plan on taking a digital test tomorrow morning . I’m hoping to get a BFP. Currently 21 DPO. Any one else ever get false negatives before a positive? I’m hoping that I just tested too early. My period is usually never more then 1-3 days off. Opinions or story’s are welcome! I have so much aniexty thinking about taking this digital test tomorrow morning because of coarse I just want a BFP so badly . Baby dust to all! ❤️
