My sister is 30 weeks, and is in a fair amount of pain - she said she's pretty sure bubs in engaging because of where she can feel the pressure.

Is this normal so early? The reason I ask is she's fairly sure she's up to 4 weeks further along than the doctor says, judging by milestones and general feelings compared to her last pregnancy. Her fundal height is also 2cm higher than the doc said it should be for 30 weeks.

Can anyone shed some light on this?
