Weird symptoms/sudden weight gain

Hi! So I just stopped taking DIM and started taking prenatal’s to prepare my body to try to convince in a couple months. It’s been about 3-4 weeks since making these changes.

A week before making these changes, there were 4 days of me being constantly nauseous and had a strong aversion to coffee and alcohol. So we thought I was pregnant but I tested negative and had my period 2 days early.

Now, I’ve gained 3lbs in 8 days out of no where and my hands are swollen. I eat healthy and workout regularly. The only thing I’ve changed is my supplements. I should have my next period next week. This is the most I’ve weighed ever. The weight is in my lower belly.

I’ve been trying to eat even healthier the last couple of days with no changes and I usually notice a difference quickly with my body but I haven’t.

What could this be?
