Uterine scarring or hormone imbalance?

Hi, I've been having trouble with my period since the birth of my baby this time last year. When I first went to the dr for blood tests in January hy said that I should be getting flushes etc. as I hardly had any hormones in my blood. He gave me hrt to start my period which didn't help so I started with Clomid (which I heard could help, and it did) but the months I took it my period was much lighter and shorter than i'm used to. This past month I didn't take Clomid and the period I got was light and only lasted one day. I googled it and found that as long as it's regular it's not a worry, so I decided not to worry about it, but today I got information that uterine scarring (from d&c or c-section) can cause this, so now I'm worried again. The thing is except for the reduced flow I don't have any 'menopause' simptoms associated with hormone imbalance. I get pms (headache, backache, sore breasts) but nothing out of the ordinary. I was just wondering if this happened to anyone else?
