I had some mild cramping (like period cramps except a lot less painful) some brown discharge (only noticable when I wiped) about 4 days before AF is set to be do . Lasted About Two Days Then stopped , now no AF . I thought it was just an earlier period about to come on . But no flow picked up. Now I'm late. I have two kids and never had IB , yet I have all the signs for it. ...... has this happen to anyone else and they ended up getting a + ???? ---EXPERIENCES ONLY.
