Don't worry hun, our bodies are really good at remembering things, like muscle memory, people who used to be very muscular and then stop training will find that when they go back to training they gain muscle mass and size back much more quickly than it took to gain it in the first instance. That's what's happening in a round a bout way. You probably still have some bloat going on too.
I'm sure you look amazing.
Re: 3 months pregnant and huge
In regards to the original post, I am just over 3 months with 2nd baby and I am huge. Was this size at 6 months first time around. Think our muscles are just weaker and as previous replies stated our bodies remember where organs were pushed to etc.
If it is the 20 week ultrasound then I agree it should have been referred to as an anomaly scan, but there's no point in nit picking, we all know what she meant
