Quoting Katie & Clay's Mommy!:" Here she comes again. This time at least she's sticking to a somewhat normal schedule. Now I've had two ... [snip!] ... for right now but in the next hour or so she'll be in my face taunting me for the next friggin 5 days. I hate that bitch!!"
It really depends on how long your luteal phase is, anything shorter then 10 could make it harder to get pregnant. From January of this year and going back last year my cycle was between 28-30 days long after I had my d&c. But when February hit my cycles started to get shorter for some reason for two cycles Feb. being only 25 days and March only being 16 days long which is the shortest I have ever seen my cycles. I did end up having two period in the month of March, which happened to be the cycle I got pregnant. It could be just your body getting back to normal (which if I remember correctly you m/c some months ago right?) I honestly believe that was the case with my body, it was just trying to get back to the way it was before I m/c. Sorry the witch showed up on you.
