Miscarriage

I recently miscarried on the 23rd of April and I have yet to start a period. I’m coming up on my 6-7th week post miscarry. I’ve been sexually active ever since two weeks after it happened and I’m just not sure if I should be worried that I could be pregnant again or if my body is just taking a long ass time to recover... should I make a doctors appointment to make sure all my lady bits are as they should? Or should I just wait until I start a period?
