Super Low/Head Down at 30 weeks

Looking for other women’s experience of this please.I’m 30 weeks exactly,at my 28 week check up I was told baby is super super low,Tech was so low in my pelvic area for ultrasound that it hurt.Baby is great,kicks & punches all the time & I know from my ultrasounds she is very active.I’m prepared to go early due to other issues however yesterday & today I’m feeling a lot of pressure,like a lot of pressure.It’s really low in my lady area like I want to actually hold it up somehow(I know that probably sounds ridiculous but it’s the only way I can explain it)I’ve had a few sharp sting like pains in my lower abdomen area coupled wit backache(But I have this anyway,it’s just a little more painful).My breasts have began to ache quite badly recently too,just like the breast pain you get in very early pregnancy.I have an appointment in 2 days & will bring all this up but just wondering if anyone has any insights for me or experience of this?FTM so I may be overreacting,I’m just wondering if this sound normal?Could baby be engaging already?I really hope to keep her in there for atleast 6 more weeks
