Two year sleep regression??

Is there such thing as a sleep regression at two? My toddler turns two end of july and use to sleep through if not wake only 1-2 times.

For the past 4-5 days she has been waking up constantly and wanting us there before going back to sleep as well as waking up at 4am and not sleeping for 2 hours before falling asleep again 🤦‍♀️🤦‍♀️

I am expecting my second child in less than two weeks and this has got me going crazy!! If you have been through this at this age how long does it go on for before it goes back to normal!!!
