Frustrated ...

Because I should be on day 4 of 5 for AF but I'm not. I've taken tests and nothing. Everything has been out of wacky since I stop my BC nexplanon. It's been out 3 months. My husband really really wants a baby and so do I but trying is sooooo stressfull. We didn't try for my 3 yr old. He just happened out of the blue in like a month. It just has me feeling down.
