disappearing symptoms

I had lots of symptoms from 1 dpo to around 7 dpo. but yesterday and today, my symptoms have almost disappeared. I was having horrible gas/bloating. sore/swollen boobs and nipples. mild cramping, and a really bad stuffy nose( which was the reason I tested when I was pregnant with my twins). but now, they've pretty much gone away. I still have sore boobs but nothing like they were a few days ago. still a little gassy and bloated but not horrible. and my nose is stuffy on and off. but I've been an emotional wreck today.I'm about 9 dpo ( I think) and I'm getting really discouraged thinking I didn't get pregnant again. and I'm honestly thinking about not ttc anymore after this cycle if we don't get pregnant.

has anyone ever had this happen and gotten their bfp?
