Try not to stress about it. My cycle went completely back to normal after having a m/c - it arrived exactly 4 weeks later & continued in that pattern. If you feel ready to try again and your doctor says it's OK to try then go for it. I felt more in control of things when I TTC'd again. Most people who've had a m/c go on to have a perfectly normal pregnancy the next time around. Best of luck for a BFP nice and soon for you.
