@SnowWhite1985 - I'm similar - I just assumed it won't happen this month!
I'm now pretty sure my "random spotting" today is actually AF appearing. I have mild cramps too. The bright side is that it would mean my cycle is back to normal (circa 28 days) - whereas the previous one was irregular (36 days), which freaked me out. I think it was due to stress.
We're trying to decide whether to get a private 'Fertility MOT' and if so, WHEN. It costs about £400 for the pair of us and includes scans etc.
But I wonder if I'm being too hasty. In this cycle, I had an LH surge (strong positive OPKs for two days) and a good progesterone result after ovulation (GP test at the weekend), etc.
BUT I'm 38 and we've been trying for over 6 months, so I don't want to waste time!
It can be tricky to book NHS appointments - I'm already feeling stressed about trying to get a 'day 3' blood test booked at the right time; and also get my husband to arrange his test. Whereas a private suite of tests would just get everything dealt with efficiently and with the extra reassurance of scans, etc. Hmmm.
