Finally got a BFP but I have a question

So I can’t really remember my last period , if we’re being honest I was so overwhelmed with ttc and constantly failing that I just said forget everything in general and I stopped tracking periods. Then Saturday I realized that i don’t remember getting a period for august and took a test that came back positive. The thing is I’ve been feeling this really weird pressure on my bottom. Like anyone every have butt cramps during their period ? Weird I know right but I’m serious lol. That’s what this pressure kinda feels like. I’ve also been having mad butterflies. Just was wondering if this is normal ? Oh yeah and I haven’t experienced any kind of morning sickness at least I don’t think so. I don’t really know what I feel honestly🤦🏽‍♀️, if anyone whose been pregnant before or currently care to share some weird crazy symptoms / cravings they may have or had would be great. Just something for me to look out for. Yes I know every woman is different and experience different symptoms but I’m just curious
