AF was due Fri, thought it would come on Sat as I had a bit of brown blood when I wiped but that was it! Still not arrived. Have looked up stuff on implantation bleeding but it seems that would be earlier than AF? Now 3days late & wondering whether to test. I don't feel like I'm pregnant if you know what I mean! I've had 2 chemicals in the 7 months we've been trying for #3 so don't want to get my hopes up.
