Pregnancy symptoms back again

Carolyn • 1st time 🤰 & waited so long for our little blessing. Can't believe this roller coaster of emotions of 1st time moms. 😁
I've had a few weeks of good night's sleep around weeks 15-17. But now in 18th, heartburn seems to have intensified. And I have no comfortable positions when lying down at all. I got a snoogle pillow which helps a bit. But I still find myself tossing & turning and sometimes having bad dreams. There are days when I switch and lie on the other side of the bed. I sometimes dread having to go to sleep because of all these.
Anyone having the same symptoms? It is like first trimester all over again. :S
