Miscarriage?

I’m on birth control and on July 7 I missed a pill then on the eighth I took it pretty late, never doubled up, but was back taking them regularly; had sex for like a week straight from July 6 to the 12th. I skip periods and a week later I had brown spotting that lasted about 2 days, cramping, then nothing. On August 19 I started back spotting brown blood that turned into red blood about 3 days later with really bad cramps. I was spotting blood a little heavy so I called my OB and she told me to come in. She did a Pap test and she said she didn’t see any blood but would wait until the results come back to rule out infection. Made it home and about an hour later I had more blood appear. This was on Aug 21st. Since then up until Aug 24 the bleeding got heavier and the cramps were a bit more intense but they only come in spurts. Called the Dr. she said to let her know if it get heavier and to just wait until Sep. 8 for my appointment. So it’s currently Aug 26 and I’m bleeding heavier and passing blood clots, the painful cramps come and go. When u think about food I get nauseous so I haven’t eaten all day.

Do you think this could be a miscarriage? What were you symptoms?
