I had a mmc in September and after thinking I was out this month got a faint positive on a Walmart 88cent test. Went and got a 5 pack of clear blue to confirm and saw a line clearly. But now my lines don’t seem to be getting any darker. I have no idea what DPO I am. Both my apps had different ovulation dates. I’m worried about a chemical. Anyone have similar lines and been ok? Calling my OB on Monday to schedule blood test. Dpos are based off Premom app.
