BFP right after period???

Melissa

So I took a pregnancy test on Saturday the 19th just in case because hubby and I were gonna be drinking and it was a BFN. I had just ended my period that Friday. This morning after sex I was bleeding and I thought that was weird so rn I took another test and it was a BFP... my period was on time and lasted my normal six days

Any thoughts?

Every test I have taken prior have been stark negatives and now I’m concerned of a miscarriage
