Miscarriage?

I was 7-8 days late and then on a Sunday evening I started bleeding heavily (which is normal for my 2nd or 3rd day of period), bled on day Monday and Tuesday morning spotted once and was done. It was heavy and thick with no huge clots. My husband and I are trying for my third (I have 2 from a previous relationship and he doesn't have any children) with my first 2 it was super easy to get PG but my husband and I have been trying since May and nothing. :/ help/advice?
