So I've been getting very faint lines for two weeks now. They're not getting any darker even though I'm using FMU.

In April I had two very heavy periods with four days in between. They both lasted over 7 days. (I have PCOS btw.)

Is it possible that I had a miscarriage and the faint lines I'm getting (on all brands I use) are from that?

Or maybe I just need to wait and test in a week or so because my hcg levels aren't high enough? I've seen women on here say they didn't get positives until like 8 weeks.
