I just got off my period yesterday, I came on my period on cycle 27 which I usually (always) been coming on cycle 29. I never been late since my last cycle that was due to me stressing and not getting my BFP! Who can tell me what this is? It's only a little coming out my vag it have a little bit of brown in it, I had chest pain today, bad breast pain, pelvic pain, back, tiredness, ache, everything pregnant symptoms has..
