Frustrated

My period came today, well im spotting. I don't know how to let God do what he does best, I have 3 kids, which 1 is for my husband, we want a baby girl so bad, it's been my prayers for 3 years. We've had an ectopic pregnancy 3 years ago and it devastated me. I keep feeling all these feelings which get my hopes up, even the kids and my Hubby, because everyone is waiting on that miracle. This is beyond frustrating, is anyone else going thru this or has gone thru this, I need some encouragement.
