text: You should probably talk to a doctor for real advice but i'll tell you what i think know. A friend of mine has a similar problem, and she was also told that she may find it hard to concieve, her periods can be very erratic and heavy and painful. Its certainly possible you had a miscarriage but i want reassure you not to worry. I believe about a third of women have a miscarriage at some point, most very early in pregnancy and most women will not even be aware they had had one or were pregnant in the first place. So without being the doctor that examined you, i can't be sure if it was a miscarriage or a heavy period, i'd suspect the later as that is more common than you might think but if you have any doubts i'd recommend you speak to your doctor. x
