Help - Pelvic Pressure

I’m jut 24 weeks pregnant and over the past couple days have felt movement extremely low down, almost in my vagina / cervix. I feel like I have a lot of pressure really low down in my pelvis too which feels quite uncomfortable.

I have also noticed an increase in discharge just sort of watery, not loads but more than I have had so far.

I have also experience back pain quite low down, a dull ache almost like period back ache.

I’m slightly worried as to what’s going on, I phoned midwife and she says the movement in my cervix may be because the baby is breech and shouldn’t be anything to worry about but I can’t help it.

Is this normal?
