Hello doctor... I am 24 and my husband I have been trying to conceive for 11 months. In Dec, my period was late for 19 days, tests were negative even ultrasound didn t pick up anything. Since then, my cycle has been messed up. I think I am a few days late now. I have this brown discharge which has a bit of an odour to it. And I have sporadic back pain. At times, I feel what seems to be fluttering in my tummy. I have picked up some weight too and I constantly feel tired. Could I be pregnant or could this be a phantom pregnancy?
