Sex Drive Dive

So every since we found out that we were expecting, our sex life has declined. This is not our first rodeo so I have no understanding to what happened. At first, we were like rabbits... now it's like 👀😕 I don't want to loose our flame throughout this pregnancy so are their any suggestions on what I should or should not do? This is only the beginning... I have a long time to go, I'm only 5 weeks & 3 days😯
