Third Trimester Rant

I'm just over being pregnant. I know it's super normal during the third trimester. I'm almost 37 weeks. I have been on bedrest since 33 weeks because of preterm labor. I have contractions all day long. Some hours I can barely feel them. Some hours they are 3-5 mins apart and are super strong. But my cervix doesn't dilate. My back is killing me due to the constant contractions. I really wanted a vaginal birth with this baby. Baby girl is measuring larger and ahead. She is currently measuring at 7.5 lbs and 38 weeks at my 35 week u/s.
