In need of alil comfort an help.

I was rushed to the er on Wednesday last week. Finding out that I had never miscarried as I was prior told by a different hospital a month ago. I was around 12 weeks pregnant. My tube ruptured. My Dr didn't remove it said he's hopefull it will recover. I left the hospital on Saturday an been on med and in bed since. Only getting up to use the restroom or get something to eat. During this time I've been home I've managed to gain 16 pounds 😣 and my legs are very swollen. I have to return to the hospital tonight to be checked per my Dr for blood clots. Has anyone experienced the same symptoms? Did the weight gain go away? Was it from the surgery an swelling? Any info is appreciated. I'm concerned an feel alone.
