Earlier in the month of July, I thought I was on my period the first week of the month, like the normal routine. However instead of bleeding like normal, I was spotting for 6 days. Then at the last week of July I began to have my period, bleeding regularly, but it didn't stop after 1 week like how all my periods did before. My period has continued to flow onto the first week of August, bleeding anywhere from medium to heavy flow, the same as it did the last week of July when I first started to have my period. Why is this happening to me, when it never did before in my years of having my menstrual cycle? I am sexually active, and am trying to conceive. Could this be a miscarriage?
