Desogestrel pill and weight gaining

I started taking desogestrel for Endometriosis symptoms, I was having a lot of fatigue and thought I would try altering my hormones. I saw on the packet that the pill contained lactose but after a google search I was fairly confident that it was a low enough level to not affect me too much (I have had quite a lot of gut symptoms due to Endo and eliminated a few foods, lactose was one of them). After being on the pill for 3 months I was sure that the lactose has been causing some significant side effects, including less control over my bowels. Through an e-consult, I requested a version of the pill that didn't contain lactose. It turns out that there is not one single oral contraceptive pill that does not contain lactose! This is unbelievable to me and I believe there should be more awareness of this.

Not a good experience, lots of weight gain, more emotional/moody. cant wear contacts anymore

I’d been off contraception for years and I wanted to go back on it as in a relationship and not TTC just yet. So far it seems to be okay th first 2 months was where i experienced most my symptoms mainly have settled sort from sex drive, headaches, no periods they still exist on month 5.
