Question: I usually have regular periods 31-34 days however I am currently on day 45 of my cycle. I have taken several home pregnancy tests over the past 2 weeks, all have been negative. I visited the Dr last Saturday (5 days ago) and had a blood test which confirmed the negative result. For the past 3 days I have been experiencing abdominal cramps off and on with diarrhea. What could be causing the continued delay in my period and is there anything I can do to bring it on? Also to note, my partner and I have been trying to conceive, we have recently returned from 4 weeks traveling in different timezone and I also, without thinking about the contraindications took a sleeping pill (tramazepam that wasn't prescribed to me, a friend had passed it on - not my smartest move) on return from our trip to aid jetlag - which I am worried may have had something to do with this change in cycle.
