Uterus/low abdom pains?

Has anyone had specifically uterus and/or lower abdomen pain from drinking Soylent regularly? I started having it twice, two separate instances of drinking it 1-2 bottles 5-6 days a week. I only noticed it the second time since I restarted it.
I’ve also read that too much soy might not be good for people with uteruses?
Any info would be great because I’d love to restart drinking Soylent regularly but I’m worried about my health at this point.
Thank you!

It is the first time I’m hearing of this. I have information to help directly.

But, I would suggest you to post on the Soylent Reddit. It is way more active than here. Worth the try for sure.
