Had mc/ on Feb 20-- when can we try again

I was 6 weeks 6 days pregnant on Feb. 20 and discovered at the ultrasound appointment it was a blighted ovum.   My doc thought I may also have ectopic (there was funny fluid around my right tube) so we had to do a D &C and laparopscopy.   Luckily, it wasn't ectopic, but she found endometriosis and removed it (so the lap was worth it).

My cycles are normally 26- 28 days.  

So can I expect my cycle to start around March 20?  If so, can I use that cycle to start again?

I am a 32 year old healthy woman.   My cycles are pretty regular (not longer than 28 days, not shorter than 25 days).   I am not overweight or underweight and I eat well and exercise regularly.  I heal well. But I have been battling infertility for 3 years.   I believe my obstacle was endometriosis (which I had a laparopscopy done in dec to remove and then again in Feb). This pregnancy occurred the month after the 1st lap.

I understand the blighted ovum is natural occurence.  I have come to terms with that and look it as a "trial run" for my body to prepare for a full term pregnancy.    

Emotionally, I feel ready to start again.   But is there any reason I should wait for ANOTHER cycle? I really don't want to beause it has taken me 3 years to get to this point.

Lea2001,
some studies suggest that to minimize the risk of another miscarriage, ideally one should wait several months after the completion of a miscarriage before getting pregnant again.  in my practice, i do not recommend this, because the risk of a repeat miscarriage in this one study was only slightly higher when women became pregnant shortly after a miscarriage.  on the other hand, women's fertility declines, and chance of a miscarriage increases as she ages.  so, i would recommend that you try to get pregnant right after you start cycling again, and when your hCG levels decrease to zero.  
i hope the endometriosis was the cause of your infertility, but often, when doctors find only minimal or mild endometriosis at laparoscopy, the endometriosis is a result of rather than a cause of infertility. every month that you don't get pregnant, some endometrium (the tissue lining the uterus) flushes out the ends of the tubes, at the same time it flows out the vagina to form a period.  your insides provide a perfect setting, warm, rich in blood supply, dark, for the tissue to grow. this is endometriosis.  so if you don't get pregnant after four to six months, you should begin treatment for unexplained infertility, even thought the endometriosis has been treated.
