Brain fog - advice or an ear(eye) needed

[FigBatSue]

Morning all,

Looking for some advice/somewhere to vent.

Currently TTC#2.
I had the implant in previously and had regular 30 day cycles. Once I had my implant out, my cycle remained the same. I then had a chemical pregnancy in August, and it was 38 days before my next cycle started.
I'm currently in CD47! 😣 And no sign of AF showing up anytime soon. I've tested regularly since CD30 and all with BFNs, I haven't tested since CD43 as feeling very deflated.
I take metformin/insulin for Diabetes, and as far as I'm aware, metformin is used to help those with PCOS ovulate?
We last DTD on 17.10 (due to work and life), if I had ovulated around this point, would it be too early to get BFP?
At what point should I speak to a doctor if AF doesn't show?

Sorry its a bit of an essay, I'm at a loss of what's going on and haven't really got anyone other than DP to discuss this with!

Hi 👋 I don’t think I can be much help but I didn’t want to scroll and ignore without offering up some advice. Slightly different situation but I came off depo shot a few month before my wedding and no clue when I would get a period. In the run up to my wedding I started using OPKs because I knew it I caught ovulation I would expect a period. Peeing in a cup every day was a pain but it was worth it to understand my cycle quickly when it came back and the tests were fairly cheap on Amazon!
I know this doesn’t 100% relate but I thought maybe I could suggest trying OPKs every day? If you’re not ovulating then you can speak to dr about that too and have all your results. Hope this helps x
