bending over!

Im a first time mom & im 16 weeks pregnant now. Just now I dropped a pen below my table and I bent over to pick it up. Note: I just picked it the pen up while sitting on my chair. Now Im a bit worried that I might hurt my baby as I feel like im squishing my baby! 😭 I felt a little pressuse on the right side now. is it okay to bend over or I need to be extra careful next time?
