To stay on hormonal BC or to live freely and have no chemicals?

Bonnie
Hey Girlies- 
Ive been on birth control since i was 15- am now 18. I was on the pill for a year and have had the implanon for two years. 
During this time ive been in 3 commited relationships and have not been using condoms- have been tested and am all clear 💪🏻 
But im not commited at the moment and am okay with being on my own and just enjoying life and the start of Uni- but im kinda sick of not having my period and getting it every 4 months or so- its pretty gross by this time and i wanna let my body do its natural thing for a while. 
But theres also the question of keeping myself safe during uni- im hopibg that this eill be a gun time of exploration for me and cannot decide if i should trust the condom or stay with the implanon and condoms... 
Any opionions and personal experiences? 
Xx Bon
