Is sex ok???

Tomorrow I will be 7 weeks pregnant with my rainbow baby. I have a doctor's appointment set up but not until next month. Im scared that because I had a miscarriage over the summer that SO and I should not have sex until Im past the clear? I also have 2 children already and no problems with them. Iv looked into it a bunch but all i keep coming to is talk to your doctor.. but I cant until next month... ya im inpatient lol.

I guess Im just looking for opinions and your experiences.
