This is pregnancy number 3...with number 1 i went 24 weeks without having to hairtie my button on my pants....with number 2 I went 19-20 weeks....and here i am at 6 weeks opting for yoga pants because my regular work pants are to tight and some cant even button....zero weight gain...i know yall arent doctors but is this normal? Should i be paranoid at the chance of multipmes?(no history of them, but this baby was a mirena baby so not exacy planned so the paranoia is real)
