TMI but in much need of help!

Chantel

About a few days ago i had a light pale green discharge and that evening, i had extreme pelvic pain as if baby was pushing his foot out or his head. But it eventually went away. Since then, i had a scan and he is fine but she said he is drinking alot of fluid. But she said i should just drink more water. Ive been having hip/back pain on the left and more discharge but this time its a very pale yellow. Just asking for some advice.

Im currently 26 weeks and 4 days.
