I'm in the same boat as you hun. I go for my twenty week next Thursday and you've basically described my most recent fears. Try not to stress cause that's definitely not good for you or baby. A friend of mine said she spoke to her midwife about belly and back sleeping and she was told not to worry. That your body will wake up if there's an issue. Kind of like fainting when blood flow is low your body would alert you if you were cutting off circulation to your lower half...normally in the form of leg cramping or spasms strong enough to wake you right up.
When it comes to movement I've felt the same way. Moments when you think you feel something but then not sure. I think once it really happens you'll definitely know. Then if its always kicks in the bladder or ri s you'll wish it wasn't quite so often :-)
Good luck with everything!!
good luck on your scan tmwr im pretty sure that everything is well & maybe wht you been feeling is actually the baby
Yes I am in the plus size area. I've worried myself because I have a body pillow I sleep with but still end up waking up half way on my stomach...so I'm always nervous that doing that effects the baby.
Ur fine baby is fine first time moms don't really feel movement till like 22 weeks and if u are in the plus size side maybe further along. I didn't feel my first till 22 weeks.
