should i stop having sex ?

so i’m 7 weeks pregnant as of today. since about 5 1/2 weeks i’ve had off and on bleeding. it’s varied from spotting to a light-medium flow. my last ultrasound was last friday, baby was still there, and everything looked fine tho we weren’t able to locate the yolk sac (i had a ultrasound before that where it was visible) but my dr didn’t seem too concerned and said it could just be the angle so i have another ultrasound this friday to check again. my doctor hasn’t told me i’m high risk or that i have any restrictions, he has only told me to “take it easy” and that we would be watching this pregnancy closely because i’ve had 2 losses before. i’ve noticed that the spotting seems to be happening mainly after i have sex. my doctor never mentioned that i shouldn’t be having sex so i honestly never thought about it. i plan on calling tmrw since they’re closed today but has anybody else been in a similar situation? should i just play it safe and stop for now ?
