I can 100% empathise with this, I waited and waited and waited for the right time to start TTC and that month my periods disappeared. I was diagnosed with PCOS and embarked on months of tests and scans before I could start using Clomid. I was angry with my body, angry at my husband for wanting to wait until the right time, and angry at anyone who was pregnant! On top of that, my DH has a daughter from a previous relationship and that pregnancy just 'happened', so his view of pregnancy and conception made it even harder...
My BIGGEST piece of advice (so much easier said than done) is to not make much of 'symptoms' when you're trying. In my experience, early symptoms can be related to anything, and if you google something you're bound to find someone talking about how they experienced that as well. All this does is build expectation and makes is even harder when AF shows! Enjoy BD'ing, but then try to take your mind off it...makes the months go so much quicker!
