Pre BFP symptoms input please :)

Amelia
Hi ladies, this is my first post on here. My partner and I have been talking about trying for about 6 months now but I went back to school as a mature student so it wouldn't be the most ideal timing. We used the withdrawal method for about 6 months very successfully. But since my last cycle we spontaneously said we would try for this cycle while we are on our anniversary trip away.  I'm now 5 dpo and for the last few days been seriously bloated, nauseous, tmi diarrhoea, more sensitive nipples, gone off drinking at all and haven't really felt hungry at all which is very unusual for me. I've a few days ago I also felt backache and aching/cramps mildly in my uterus as if I was about to come on but they have gone now. I was wondering what anyone else's symptoms before getting a bfp were?
