I get this every other day but not constantly. Sometimes it's sore to walk even. Im 28wk also
If you dropped it could mean baby will come in 4 to 6 weeks but not all women have this happened to them so within 4 to 6 weeks you can give birth or go fully to 40 weeks.
Some women do "drop" earlier than others, but it doesn't necessarily mean you will be in labor soon. Some pelvic pressure is common with a growing baby. If you feel concerned, call and talk to your doctor. It never hurts to ask questions and it will give you peace of mind.
Good luck Momma!
Thank you all gotta appt thurs hopes all well
