Definitely start getting seen. The process is a total pain, but do it. If you go back to the same doc, same info, it should be easier, no?
Its harf I've had a few miscarriages but don't wait to see a doc. Sometimes they can help and sometimes they can't but you won't know if you're not going.
Definitely see a doctor. I had 5 miscarriages before this pregnancy. This time I'm on a range of drugs and have gotten so much further than before! You'd be surprised how much the docs can help. Good luck!!
