Ariel
No signs of it yet but my boobs hurts a little, I get a little cramp here n there my appetite has gone down a little as well my rest time it hard for me to get comfortable I have been getting like heat flashes along with nausea at the same time making me wanna throw up. Should I just take my prenatal vitamins just to play it safe? But Yes I know like hello signs of prego but guess WHAT!!!! 
I took a test last Wednesday 11/23 but it was BFN!!!!😭😭😭😭😭😭😭wasn't going to squint my eyes to see if there a VFL. Just patiently waiting not sure what's going on. Any ideas or advice?
