Pregnant with twins, how much cramping is normal?

Question

I'm 12.5 weeks pregnant with twins.  I had a miscarriage in 2018 so I am constantly paranoid about every twinge I feel. 
 From the time of my positive test to about 8 weeks I had light period like cramps everyday. Almost felt like I was going to start my period at any moment.   Those have gone away, but now I have this almost constant achey feeling.  Not quite cramps as to me cramps feel like someone squeezing and releasing. This is just a constant uncomfortable ache. The best way I can describe it is I am very aware I have a uterus, lol.  I also feel like my bladder hurts, like when you have to pee so bad it hurts, even though I dont have to pee or only pee very little.  I had a TV ultrasound at 9 weeks and all looked good with super strong heartbeats.  My doc did an abdominal u/s on Friday but it was one of those wireless wands that goes to a tablet, not super high def and no measuring, but he said all looked good and babies were moving around.
Is this likely just my uterus stretching given I have two lime sized beans in there?
Also, on a second note... I'm not showing at all yet.  I can feel my uterus rounding out and have lost the definition of my hip bones, it just seems all the bump pictures i see are way bigger than mine. I have a really long torso and I know i should probably enjoy still fitting in my pants while I can. It's just one more thing for me to obsess over.

Answer

I am 9w4d and have had horrible cramping. I need to check my water intake. I hear staying hydrated helps!

Answer

Yes I had such bad period pain with this twin pregnancy I almost called the ambulance twice! I still get a bit of cramping like that but not as bad currently 25weeks the only thing I could put it down to was stretching every ultrasound came back fine. If it’s bad go to hospital better to be safe then sorry ❤️

Answer

I felt crampy for a long time with my first pregnancy. I was worried too after a miscarriage but now my son is a happy 10 month old 🥰. 
I am pregnant with twins now and I have been cramping every so often, which worries me but the doc was not concerned at all when I called. Congratulations on the twins! Just try to stay positive.

Answer

I cramped a lot in early pregnancy. I still do every now and then. I’m 23 weeks. Make sure your staying hydrated. Mine get dramatically worse if I’m not hydrated.
