Major pregnancy changes after MC

Hey ladies,

I’m currently 5 wks along with my rainbow. I have a 20mo, and I had a missed miscarriage in September at 8 weeks. So I never got big, nor were my symptoms severe with my angel baby, but the symptoms I’m having now are much more severe than when I was pregnant with both my firstborn and my angel. I’m already feeling HUUUUGE, and my boobs are killing me. Like seriously, I can’t wear my jeans anymore. I’ve heard that you can show earlier with subsequent pregnancies, but I got to 8 wks 6 days with my second and didn’t feel as big as I am now at 5 weeks. Could I just be a third pregnancy kind of thing? I’m already trying to push out thoughts of twins, but it’s hard to dismiss. I have my first U/S on 2/8, so I won’t find out for a few weeks, but has anyone had a similar experience? Did anyone actually end up with twins? There’s no reason for me to suspect it since only fraternal twins run in my husbands family, and this was a natural conception. 🤷🏻‍♀️ Just wanna get some of your opinions.
