7 weeks

I had a chemical pregnancy in July and we finally got pregnant again in March. I am 6 weeks 5 days. My husband and I had sex for the first time since finding out we were pregnant. No pain we took it easy but now the next day I am bleeding. I'm scared. Is this normal? I am not having any pain with the bleeding but my boobs no longer hurt like they have been for weeks. I did feel nauseous earlier in the day but that to has past.
