So, in Nov last year I had a mmc at 13 weeks and a subsequent d&c. My ob said to wait for 3 periods before ttc, which we have done. I've just got AF from our first month of ttc, and I'm upset as you can imagine, I so desperately want a baby brother or sister for my little boy to play with. He'll be over 3 yrs old by the time any next one is born, if one comes along, and I'm just so anxious that it never will. He's such a generous and gentle little boy and I just can't bear the thought of him being on his own. The thing is my cycles have been such different lengths since my mmc (33, 23, 27 and 19) and I'm worried that, well I don't know, that they won't return to normal again and I won't be able to give my DS a sibling. Has anyone else's periods been very random following a mc? And how long until they come back to normal? Am I likely even to have o'd with a cycle of 19 days?
