Menstrual changes with the shot

I’ve been on generic semaglutide going on 3 weeks now. I took my 3rd dose Tuesday .25. I’ve always had irregular periods. Always late. very rarely do I get a period on time. usually 2 months sometimes longer in between a cycle. Since I’ve started the shot I’ve been mainly spotting with some heavier bleeding basically daily. Might be fine for a day or 2 but always at least spotting. it’s kind of annoying! I know I have read that other women have experienced changes with their menstrual cycles while’s on the shot I’m just curious if it ever evens out? or am I just going to be dealing with this as long as I’m taking the shot? Any other ladies have experience with this?
