just looking for a little information?

Okay so this is my story I know I need to go to the doctor to get accurate results but here ago I had a miscarriage back in May my boyfriend and I have been trying since then I know it's only been a few months but usually my periods last 4 to 5 days this month my period was only two days and then spotting on the third day and I'm worried that something might be wrong is there a chance that the miscarriage might have hurt my chances of getting pregnant?
