Yes I'm aware Slynd doesn't have estrogen. But everyone's body will respond to different forms of contraception. You shouldn't make your birth control choices based on other's anecdotes. You should talk to your doctor about potential side effects and what the quantitative risks actually are and see what's right for you.

Edit: I should add- Drospirenone is also likely the most thrombotic of the progesterones, probably a lower risk than estrogen containing pills but I wouldn't recommend using it if VTE is a huge concern- It's likely safer to take a different form. However, if it it's the one you tolerate the best it may be reasonable to assume the small but higher risk of a VTE, the data is still murky.
