Hi everyone,

Last weekend I posted a poll asking if this was my bfp. It was the faintest line but it was there. (Top photo)

Got excited and then kept testing, lines were getting lighter. (Monday test then Wednesdays test this week) (middle photo)

Had bloods done yesterday and it was negative.

Today I decided to take an opk, which is almost positive (my phone is crap and the line looks darker in person) (bottom photo)

What is going on? I'm 5 days late for my period, cd 35 and maybe I'm ovulating?

I should add in the last month and a half Ive lost 15 kgs. Could this be the reason for delayed ovulation? My partner works away and I'm seeing him tomorrow night. Should I dtd/bd??
