Hello!

This is my first post so please bear with me. I have PCOS (diagnosed over 5 years ago) and my husband and I have been TTC for over 1 year for our second child. I got pregnant in 2015 and had a miscarriage and shortly after I had the nexplanon implanted. I had the IUD removed last July and have been TTC ever since. In Oct 2016 I started on Metformin and have been having regular af ever since until now. I am 5 days late and I took a pregnancy test this morning which was bfn. Should I wait a few more days to test again or should I just think that my hormones are all out of whack again and I am really not pregnant?
