Last period was jan 8-14. Had sex jan 15. I am now 11 days late. I took a test two days ago and it was very clearly negative. Ive been spotting like pink/like brown for like 3 days now. But its like barely visable on tp. Should i still consider pregnancy as a possibility?

Whats the latest you got a positive? Do i still have a chance to be pregnant?

*i dont know when i ovulated
