I didn't have an ERPC, but a natural miscarriage and am now 8 weeks pregnant, having conceived within 2 weeks of the miscarriage finishing.
And this is not the first time this has happened - DS2 was conceived to a similar pattern.
TBH, there are pros and cons: it's not quite so easy to date (or at least, it's not so easy to convince midwives/doctors of dates even when you know full well exactly what has happened) and in my case, this is by far the most exhausting and draining of all my pregnancies (although that might be because I'm 39 now, not 32). I have effectively been pregnant since the beginning of August, with a brief gap, and I'm still nowhere near the end of the first trimester! That's draining.
On the plus side, having DS2 was a very effective emotional closure for me after the first miscarriage, and there is a school of thought that conception is easier after a miscarriage because your cervix is still slightly open.
As for the MCs after you've had DC, yes, sadly, having had a successful pregnancy is no protection against subsequent MCs. If you ask around your friends with children I'm sure you'll find a shockingly large number have had MCs and many will come after the first child. Each one is sad, of course, but they are still the minority of pregnancies - if you get pregnant again you are much more likely to carry to term than to have another miscarriage.
