5 weeks 3 days and starting to worry

I know I shouldn't, but here I am worrying about my baby who's growing inside! This is my third pregnancy. My first was a chemical miscarriage, the second was a healthy baby girl and now here's the third! We just found out on Sunday so it's been a cautious week of telling our 13 month that she'll be a big sister (knowing she won't remember lol), thinking about life with two little ones but then also that feeling that we need to be cautious about how excited we get because You. Just. Never. Know. (No one else knows... Well, except for you now... Yay for awesome strangers! 🤣)

I have had nausea and being hungry all the time since Saturday. Then this morning I had diarrhea literally 9 times before lunch. That's when the worry set in. I've had dull cramping off and on since the afternoon. Could it be residual from all of the diarrhea? Maybe. I keep reading that some cramping is normal. I have not spotted. I did spot with my daughter which led to an early ultrasound at 6 weeks and then the discovery of a cyst on my right ovary. I later needed it removed while 16 weeks pregnant! I'm working with one ovary which clearly is doing just fine! Just praying for a drama-free pregnancy 😍

Anyway, just feeling achy in my hips and lower back but also low, left near my vagina. Nothing very painful but dull and enough to know they're there. My first OB appointment is in one week! I think it's all normal especially after the day I've had, but just hoping to get reassurance and your perspective or experience! TIA! Praying for a sticky bean! The first trimester can't go fast enough 🤗
