crazy baby fever

so My husband and I have been ttc for a few years now and I've always brushed it off that we haven't been able to yet but lately it's just been hitting me more and more and I see some moms aka my cousins gf pregnant smoking and drinking and saying stuff like I don't even want the kid it's messing my life up and I can't help but get angry. my husband and I would be awesome parents and we really want a baby so why does she get one and not us its breaks my heart! I was walking around target and ended up at the baby section and I couldn't help but cry just looking at all the stuff I may never get to buy...my period is due in two days please everyone help me pray that this is it that God has finally given us a little baby. 💔
