Positive then negative? 😔

Morning! 😊

Periods due today, this month we’ve had a lot of stuff going on so haven’t really worried about ttc too much, still did opks and made sure we did the deed lots 😉 but I tested yesterday anyway! I actually forgot I’d done the test and left it in the bathroom and ended up going back to it about an hour later and it was positive! Faint but definitely pink!

Done another test today and there’s no sign of a line whatsoever 😔

This mornings negative-

Is the positive a dud? Any chance I’m pregnant? 😩
