Daisy - with the first CP - I had enormous and sore boobage, but no idea of the stages of a monthly cycle / fertile times or anything else really I think I tested on day 26 of a 29 day cycle, got the BFP and then bled the next day, so AF came early and was heavy and clotty.
The second one was 13DPO as I hate the thought of early testing. I was fairly certain though, as I'd had obvious implantation cramps, a bleed and fizzy boobs
Third one - I didn't test till the day AF was due. Again, I was fairly certain - mild thrush, raging insomnia, night sweats, mouth ulcer and creamy cm post ov.
This time - I've got the creamy cm, night sweats, mouth ulcer and thrush, plus nausea, so am still hopeful. I only tested early because I've been told to contact the recurrent miscarriage clinic as soon as I suspect I am pg.
I may test again tomorrow, as I feel so sick today, but may hold off, as if I don't see spotting by Saturday morning, that will be the biggest indicator that AF may not be on her way.
Fingers crossed !
