Lessina Birth Control - help! trying to make a decision.

Alex
 I just wanted to ask if anyone has taken Lessina bc and how was their experience with it?
Im asking because my SO and I want to try something but I'm constantly paranoid of getting pregnant. And I'd much rather take a calculated risk and get some opinions rather than just dive in. 
I realize that the most effective way to not get pregnant- is by abstaining. Or after that by using two methods i.e.: bc and a condom. 
Having him cum inside would be taking a risk in every way and I should be prepared for that.
 
So I suppose I'm trying to see if anyone has had issues while taking Lessina.
