First time mom

Hi, I’m a first time mom to be. I have struggled with fertility since i had gotten weight loss surgery 2 years ago. Anyway switched my citamins and not even a month on them ended up pregnant! Yay!! I’m soooooo damn happy but also very cautious of what I’m doing. I found out saturday and damn my boobs hurt, i have a cold, been drinking tons of liquids including 75 fl oz water a day. Taking prenatals! Trying to eat enough because my stomach is smaller. I have an apt tom and maybe ill get an ultrasound 🥰🤩 im so excited maybe to even see lil bean and know its okay! But im not sure when i concieved. My ovulation is all over the place my last period was 12/12 so between the premom app and this one should be between 6-8 weeks ♥️♥️
