5 months TTC and ready to give up!!

Mercy • I'm 27 years old and me and my husband are expecting our 2nd baby in March. Our daughter is almost 2 and we are excited to be giving her a sibling!
I'm just sick of my stupid body! I am now a week late for my period and I've already taken two tests and they were both negative!  AF hasn't come yet and I'm just getting really upset and depressed! Rant over!
