Darkest line I can get

[Dodger987]

Hi! Just looking for some advice. Trying to conceive at 40. I already have a couple of DS who I conceived 1st time but I was a lot younger!
Currently starting off by tracking my O. This is the darkest line I've been able to get this month. Should I just go with this meaning that this was in fact my LH surge or is it really not dark enough to go with that 🙈

Hey! So I didn't conceive last month. Did any of you guys get a bfp? 🤗

Back on the LH strips. I've got clearblue and easy@home. Again these are the darkest line I could get on cd14.

I read that some women just naturally have a lower level that shows without it being a problem. Also I drink A LOT of water daily. Always have done 🙈 so I don't know if that's. Just weakening the tests? I've tried holding off drinking for a few hours but I just can't.

Basically wondering if anyone else has had similar and conceived?
