Question...

I had a miscarriage at 6-7 weeks on November and I am pregnant again with another baby.. I know docs call this "baby number two" even though I haven't actually given birth to a full term child. Will my uterus still stretch faster as if it was my second baby? Scince my body's already stretched a little.. Or will it just be like a first pregnancy again? Sorry please don't judge this question I just hear things from people and want to know as I'm very early on.. And am not sure if it's just bloat or if my tummy is slowly growing! (Asking cause my work trousers just didn't fit today) haha
