Anyone else not losing weight?

Hello!

I’ve been on Hers GLP1 and am not seeing any weight changes. I am a 5’5 female and lost 9 pounds in the first three weeks (started at 197, down to 188) but then on week 4, I got my period which ended up being the worst, my painful period of my life. I’ve read that other women have rough periods in the beginning of taking a GLP1 so I’m not too worried but, since then I’ve gained a pound and have stayed at 189 for weeks. I’m on week 6, am in a calorie deficit and have switched to a healthy diet with plenty of protein and fiber. I’m drinking water constantly and staying hydrated but the weight is not budging. I’m wondering if it’s hormonal. Has anyone else experienced this?
