I need advice


I had a miscarriage in July. Bleeding started on the 14th, I passed the baby on the 17th and bleeding stopped on the 23rd, I was 8 weeks but baby only measured at 5 weeks, all my symptoms went away when I started bleeding, I have had u protected sex every other day since, I'm getting symptoms again, could I be pregnant? I don't have anyone else to ask and my doctor is no help at all
