ClearBlue Digital Help!!!

Brittany

Hi guys! I’m looking for some help with the ClearBlue Ovulation Digital. I had a miscarriage in January (6 weeks out) and On Monday my HCG was down to 15. I was thinking it was fully gone by now and I thought I ovulated before I got my period. So I decided to take a ClearBlue test which showed not fertile but when I popped the test out, there were two lines. Do the lines mean I’m close to ovulating? Sorry, this is my first time using OPKs. Thanks!!!
