Ok help ... hopefully I’m posting in the right group.

I got a BFP today after Valentine’s and my period was 11 DPO Which started February 4th it lasted 3-4 days and spotting few days after so I marked it as my period I took a ovulation predictor in January so I found the peak days. It just doesn’t make sense how I got a blazing positive like 5 days after my period like I said my period was about 3-4 days and spotting I included in the chart. But I have been craving food like crazy and thought it was just random stuff. Only been with my boyfriend for four months .
