I'm almost 38 weeks and my little nugget still switches positions. My OB assured me that most babies, if not in position before labor, do turn during labor so I wouldn't worry!
My baby was transverse till 34 weeks, don't worry u have plenty of time for baby to move into right position
I had the exact same thing. The doctor saw it around 16 weeks. I'm 25 weeks now and baby moved on its own. As far as your other concern, it won't hurt you or baby just make sure you keep an eye on it. Any spotting our pain should be reported to your doctor. I've noticed that I have a lot of pressure down there as well. Doctor said that is normal as baby grows so just be prepared for that. Congrats!
Not sure about the pelvic lining but your baby has plenty of time to get into position. I wouldn't worry about that until week 30 or even later
