Sex during pregnancy

I am cleared to have sex by my doctor, but I have some questions. During my first pregnancy my husband and I were both too scared to have sex, but now with my second pregnancy we’re more comfortable with it. But now I have questions since we haven’t done it during pregnancy. I’m just about 10 weeks and I have a little belly (but it’s mostly bagels not baby!) so here are my questions:

Is it safe if I’m on top?

Is it safe if I receive oral sex?

Thanks!
