I remember absolutely losing is with (ex)DP when i was pregnant cause it was a gorgeous day and he said he'd take me out for dinner. When i discovered nothing fit y fat belly i started yelling at him to go out for dinner on his own cause i wasn't coming.
Honestly, the hormones make you crazy. I knew i was being irrational but couldnt help myself either.
Sadly, i was like this the entire pregnancy. I hope you don't get too scared by that!
Good luck with it all
