Junel Fe

I started taking Junel Fe about 9 month ago. I haven’t had a period since April 28th. I took two pregnancy test on June 15th they were both negative. would it have showed up if I was pregnant? I haven’t had any signs of pregnancy except a missed period. Should I be worried? Is no period a side effect from taking Junel Fe? I have been having protected sex & taking my birth control on time since June. I did have unprotected sex a few times in May but he never finished inside me. Help?!!
