Trouble napping

Does anyone here have trouble napping? I have never been good with naps for as long as I can remember, but with pregnancy exhaustion I do try sometimes. It takes me forever to fall asleep at any time of day, and when I do fall asleep for a nap, most of the time I wake up feeling worse than before I even took the nap! Groggy and wiped out and just ugh!! A bit scared of how it will be after baby arrives since I've never been able to nap properly. Hoping this changes though since I will be a different kind of exhausted at that point 😅
