BFP and now this...

Updates in comments***** I got my BFP last sunday at 11dpo. It was very faint. Wednesday I got another BFP and it was much stronger. Yesterday I had a touch of brown in my discharge. Today 16 dpo I have a little more brown and had a small stringing brown clot. Called OB yesterday, nurse said not to worry brown is good. The clot has me nerved though. Never had spotting while pregnant. I called and am getting seen this afternoon. I am praying so hard. I don't want to lose my baby.😢 I hope my intuition is wrong and everything is fine.
