Aw, congratulations mama! Yan talaga ang power ng prayers at consistent effort, so happy na cephalic na si baby at nandito na kayo sa 36 weeks! The pelvic pressure you're feeling is actually normal at sign na baby's engaging na, which is exactly what you want, pero if it gets really intense or you notice any bleeding or fluid loss, best to check in with your OB just to be safe. A few of my mum friends said they felt the same thing towards the end and it meant labor was coming soon, so maybe prepare yourself mentally na pwede anytime na, good thing hospital bag is ready na! Keep doing what you're doing with the left side lying at talking to baby, honestly those things really do help with positioning, and you're almost there na!
