That must have been so worrying! You must have felt rotten. How old are your twins? I had a really tough pregnancy with my daughter. I kept getting infections in my body including my teeth, so felt really run down most of the time. Then I had irritable uterus for 4 weeks and was threatening early labour. I was having contractions for the last 4 weeks and couldn’t walk or bend down without having one! It was so weird, thankfully they weren’t sore.
Could you maybe get a massage? I know it can be weird as you’re on your side for it, but might help.
Feeling nauseous is awful, I had it with my daughter too. I couldn’t lie beside my husband as his smell was making me ill, ha. Poor man.
