1st off, I am so sorry. I know how hard it is. 2nd, I bled for about 2 weeks (my miscarriage)and I did not have a D&C either. My periods for the next year were all over the place. I would even skip a whole month. My body was just completely out of whack. I was so stressed out that of course that made it worse. Sometimes it my cycle was 29 days(about normal for me) and sometimes it was 45. Everyone is different and the doctor even said I was normal. It is just hard to tell how your body will react. I was engaged at the time and we weren't being careful. After that my now husband wanted to wait til we were married. A whole year of every other month thinking I was pregnant because my period was so late only to be disappointed. I wanted it so bad. When we did finally have our wedding (1yr and 1mo from the miscarriage) I was already 2 weeks late, but knew I was stressed and 2 test were negative. Turns out that God wanted us to wait til we were married, too. Sometime that week, he gave us a little gift. 9 mo to the day of our wedding, our little souviner from Mexico arrived. Complete with birthmark on back that if you look real closely, says made in Mexico ;) I know a little more info than you wanted but I love the story. I had a whole year of confusion about my periods, but it all worked out. I know you will be frustrated, but you will be fine. Hopefully your period comes back better than mine did. Good Luck!
