Insomnia

I never have a problem falling asleep since I’m always exhausted after working hard all day. But after I get up to use the bathroom overnight, I can’t get back to sleep. Last night it was 1:40 am that I woke up and laid there for 2 hours before I gave up and started playing on my phone. Finally was tired enough to sleep like a half hour before my alarm went off so even then I barely slept. Tonight it was like 3 and I waited like 40 minutes just laying there trying to relax and not think about much but then my mind started racing with things I need to get done this weekend and about my kids starting school on Tuesday and about my ultrasound on Tuesday and so many other things. I gave up and got on here and now I’m in my recliner watching tv in hopes it puts me to sleep. Third trimester always brings it on for me but this is worse than just taking forever to fall asleep. Anyone else lose having sleep issues?
