False positive?

Hi Everyone!

I took a test 2 days ago, 1 day before expecting af. But i was having symptoms. Tired, nauseous. I got a very faint yes but today i got my period, i think. I had a miscarriage in march and just skipped my period that time and had no symptoms. So im not really sure how to gage it. Anyone ever been in this situation where they were pregnant but get a period?
