Umm...super confused

So I was told at my 20 week scan I had placenta previa and that my placenta was covering my cervix a little, but not a whole lot, and they believed it would move on its own but I have a scan in 2 weeks to find out. This was 2 weeks ago.

The doctor said NOTHING about sex and I just read a post saying you can’t have sex with placenta previa?? I had never heard of it before this scan. She came in after the scan and said “yep looks like placenta previa but your placenta is barely covering. Come back in a month to double check if it’s corrected itself or not” and said nothing else and I didn’t think to ask because she was so blasé. I don’t know if how much the placenta is covering matters or not. We have been having sex almost every day since my appointment. 😭😭
