Any women experience bleeding after intercourse while pregnant?

I am about 6 weeks along. I had some bleeding in the first week of pregnancy. It was dark brown and only happened once so the dr said it was fine, nothing to worry about. Later that week I had two incidences of very tiny blood spots, again brown. Dr said it’s fine but that I should refrain from intercourse so as not to get freaked out. I had over 2 weeks of no blood, so last night my husband and I had intercourse. I was on top to make sure not too deep. This afternoon I had two large brown spots of blood!!!! Called the doctor and she said all we can do is wait. Has anyone else had brown blood in the first trimester with or without intercourse??
