I've been a hypochondriac all my life too... Probably since I was 10 or 12...it annoyed my dad so much!
That's so great your midwife is trying to reassure you that everything is ok at this point!
So, I might have a hindwater leak.
It felt like I leaked water yesterday before going to bed and since the Drs are all ready on edge with me I thought we should go in to confirm but I didn't have any more leaks there and they did a few different tests to confirm. However, it was all negative. So we came back home and could sleep.
I was having contractions about 8 minutes apart lasting 30 seconds but they've died out now that I've slept.
Hopefully me thinking I have a hind leak isn't me just being a hypochondriac lol!!
