My doctor told me that women are usually more fertile for about 3 months or so after a d&c and obviously we still might have cycles in that time. All women are still different and so that might differ still, my dr. gave me the example of how most women are a little more fertile after taking bc pills and thats for the same reason we would be after the d&c or miscarriage its our hormones. However some women get off bc and it might take them awhile to conceive and some might get pregnant right away. So for me even though I might be a little more fertile I would just count on the fact that it might take a few mos.
