Pelvic Rest for threatened miscarriage

Be

Ok so last Saturday I woke up bleeding with cramping, happened again Sunday. I went to the ER and they done ultra sound and blood work all looked ok. Saw my ob on Monday and he put me on bed rest for the week and gave me suppositories to use for 10 days. Said no lifting, sex or anything like that. I can go back to work Monday long as no bleeding. So after I use the suppositories what about sex? My Dr didn't say a specific time frame on that
