Getting regular periods back

molly
Hi I lost my baby in April at 22 weeks. I didn't get my first period till 18/06 and then second on the 17/07 - however this one lasted nearly 3 weeks. Would that have delayed my ovulation days? I had no syptoms of ovulation other than my period stopping as quick as it came. I went to the doctors and he doesn't know why I bled for nearly 3 weeks. Anyway I feel like I'm constantly waiting for something it's horrible. So I thought last night maybe I should go back on the pill for a month or two just to get my body back regular? My doctor said he'll see me again on the 5/09 but it's a while another month away. What should I do? Any similar experiences? Please help me understand what's going on xx
