Giving up as my DPO moves along

Im 7DPO and I've pretty much given up hope that I am pregante. Ive had a couple symptoms that I have never gotten before at pms and a couple that I had during my first pregancy but now I am 8 days away from AF and most of my symptoms have somewhat subsided (besides randomly erect nipples and sharp shooting/stabby pain in breasts which started yesterday and only happend my first time around) Do you ladies ever just give up after a point? I had no issues conceiving with my first. It was the first month we decided to just see what happened and boom. Its been a few months now for us. I just dont want to be disappointed when AF shows up and im feeling like she might :\ *tears*
