Sarah • 29 • Baby Girl #1 11-3-19💕 • Baby Girl #2 2-8-21💕

So my period is now 6 days late, i had kinda bad cramps that didn’t last long and were on and off along with light spotting (pink and brown) for the last couple days. Ive had a pretty bad headache the last couple days and i was really bloated and nauseous yesterday. I ’ve taken several pregnancy test and one (a pink dye) was a little faint and the other 2 (blue dye) were negative from what i could see. I’ve been trying to get pregnant for 8 months now. Could this finally be it? Or am i just having a weird month?😔
