I've had insomnia since the middle of the second trimester. It's not bladder related (I can go all night without needing to pee) it's definitely proper insomnia.
I wake up at somewhere between 1.30am and 2am and I am as awake as though it were midday. Occasionally I can get back to sleep again within an hour, but often as not I'm fully wide awake until at least 5am and sometimes until getting up time.
I am wondering whether my brain is settling into a newborn's sleep pattern, in preparation. I can think of no reason to be so awake (no need to pee, no kicks keeping me awake) and it's not like the waking up to turn over that is such a nuisance. And it's so predictable in the time.
Mamabear: have you considered it might be
pelvic girdle pain? It is often misdiagnosed as sciatica. I have been referred to a physio who has given me some exercises to do to help strengthen the muscles that hold the pelvis together:
On all fours, arch your back upwards (like a cat) and downwards (like you're up for doggy style
do this ten times, twice a day. (OH can't watch this without getting a bit excited
Then, also on all fours, move the hips to the left and right (like a dog wagging its tail) slowly, again ten, twice daily.
on all fours still, walk your hands around to the left so your torso curves around, stretching the sides, then walk the hands around to the right, curving that way. Stop if it ever gets in any way painful.
And also, lots of kegels (ten slows ones, ten fast ones) at least 6x a day
when seated clench the buttocks (10 cleanches, 6x a day)
when seated, pull inwards with the abdominal muscles just below your bump. (ten pulls, 6x a day). I do these by setting a reminder at work. (I still forget a lot, though)
turning over in bed she told me to clench my buttocks and pelvic floor as I do the turn - that should stabilise the pelvis as I make the turn.
