Positive opk 3 days late AF and weird symptoms

[Miracledust29]

Hi, this is my first post just looking for some clarity! So my opks started getting darker almost peak just before I had to go away for work so don't exactly know if I definitely ovulated.
Few days after I had a strange rusty colour only on wiping for 6 days ending 6 days before af due and nothing ever in knickers, constant headaches so bad that one day I had a migraine whilst away with work that caused me to actually be sick, something that is so unusual for me even after a very heavy night!
Fast forward to now I am 3 days late after usually regular 27 day girly still with headaches right in the front. I have been getting positive opks since the day after due 3 days ago but all hpt tests are bfn apart from the one I will attach a picture for which I don't know if I'm going mad or if I see a slight line/shadow. Please help if anyone has any similar experience

Hi I'm currently experiencing exactly the same and wondered what the outcome was in your situation?

Hey, on that occasion I was not pregnant however I'm now pregnant just over 6 weeks and had a previous pregnancy before this which I MC. What I can say is positive opks this time around (along with a few other symptoms) were what made me test and it came up right away. I think when I made this post I was hoping for it so bad but I think when you actually are and it's around when af is due then a line should be more easy to see. Maybe try a FRER? I did also have a chemical where I did get faint lines on a test for a few days but unfortunately didn't progress.

Headaches and positive opks annoyingly do spike for me generally before AF but the ones that did indicate pregnancy were VERY dark and positive. Sorry that's not huge help it's just an annoying waiting game. Let me know the outcome and good luck xx
