Better sleep last night

I have not been sleeping good the past days. My OB-GYN told me that it's normal to feel that way. I usually get up in the middle of the night to go the bathroom and pee but then when I get back to bed it's so hard to fall asleep again. Finally, last night I was able to sleep better even though I woke up in between but was able to get back to sleep and I knew I slept better because I had dreams but can't remember them anymore when I wake up in the morning. So, I feel good today.
