BFP now a period?!

Heather

So, AF was due to start Thursday 2/21. Didn’t come, tested 2/22 FMU frer with a faint line. Then had some VERY light spotting that was dark brown. Then 2/24 I took another frer (regular and digital) and definite BFP. Today 2/25 having some red and moderate flow (like my normal period). I’ve had cramps since 3DPO and no other symptoms. I have my line progression below.

Any thoughts or has anyone experiences this? What was your outcome? 🤞🤞🤞 #worried
