I had moderate cramping and small menstrual clots signalling my period today.But there is no blood flow and I only see these bits and pieces and clots while urinating. Is this normal on periods? I used to have atleast one day full flow before but for the past 2-3 months I am seeing only clots and no regular blood flow.when doing ultrasound last month I didn't have any issues except two simple cysts in right ovary. But this behaviour I have been observing for 3 months now.I have also been trying for IUI but couldn't do last month.please advise if this is normal or anything of a concern.Its a major cause of worry for me as am trying to conceive and afraid that this might be interfering or so.
