To all my prego ladies out there

This might sound like a stupid question. Is it safe to have orgasms while being pregnant? Im a 1st time expenting mom. Currently 12 weeks & 5 days far along. When I was about 6 weeks me and my partner had sex and I had an orgasm. Ibwasnt in pain or anything. But when I went to pee I noticed blood when I would wipe and a small blood clot. I got really scared and went to the ER. They checked everything and said everything was normal. They told me not to have sex until I would see my OBGYN. So about 3vweeks went by and once I saw my doctor she told me I could have sex again so I been active again but im scared of having orgasms so when I feel im about to finish I stop my partner cus im scared im goin to bleed again. Hope Im making sense😓
