I miscarried four months ago and am yet to have my first period since. I have no idea if I have ovulated, but without TMI, I have reason to believe I might have, admittedly I am hopefull but I dont really know. For the last three mornings I have been woken up by the stomach cramps and found that I had quite bad diarrhea when going to the bathroom. I have then been fine during the day, no more cramps. I don't believe it to be caused by anything I've eaten. No other symptoms to speak of, slightly achy back but then it a possible I am looking for symptoms.pregnancy tests negative so far, has anyone experience of this?Might I be pregnant?
