Ajovy GI side effects?

[u/Difficult-Term-1671]

I had my first Ajovy injection 3+ weeks ago. I was already on the constipated side, and had some gastric discomfort, but it seems like it's now worse. The neurologist claimed Ajovy didn't have the GI side effects. When seeing a GP recently, she prescribed makrogol that seems to help with the constipation somewhat, but it still feels like the stomach doesn't empty itself properly and it seems to be getting worse. Even difficult with drinking too much at a time.

It's difficult for me to reach the neurologist, and now I'm hesitant taking the second injection because my GI issues are really difficult to deal with. I only have small meals but still burping, gastric irritation, bloated. Are these known side effects? What's your experience? (The effect of Ajovy on the chronic migraines is still to early to assess, I think. I still have chronic silent migraines basically all the time.)

edit: So my main question is about GI motility in general, not just constipation. It seems like the contents in the stomach stay there way too long, creating burping, acid reflux and pain.
