Help with contraception :)

I'm 18 & am in a committed relationship, neither my boyfriend or I like the feel of condoms whilst having sex, we have been using them until now & it stops us enjoying sex as much, however due to me having a Medical condition I am unable to have any sort of contraception that has estragen in it, what do you lovely people suggest? I have quite heavy periods as it is so preferably somethin that doesn't make them worse, any help would be much appreciated Thankyou 😊 x
