I dont think your at a higher risk of MCing again (unless there is a reason for it, like low progesterone etc) Ive had one MC and am PG now, a friend had two and now has her son.
I am pretty sure you are more likely to MC your first pregnancy (a lot of the time people dont even know they are PG, AF is just a couple of days late etc).
If you do (unfortunately) MC again if you have an understanding GP they can do some basic fundamental checks, but not all will.
Gl, and I hope you fall quickly when you start TTC again, and have a sticky healthy bub
