need help from anyone that has had complications with the NEXPLANON implant.....please im desperate.

let me start out by saying i dont have medical insurance until wednesday. i got my implant when my baby was 1 month old right after my period, then i had a period when she was 3 months and 5 months (my last one) and since 5 months i never stopped bleeding an atleast once a day i get cramps so bad they are worse than period cramps but not as bad as contractions! its been a month of that and i thought maybe it was a uti so i took some old antibiotics (not expired) for uti. usually after 4 days of antibiotics i notice a difference but theres no change. i cant see the doctor early i just want to know if this is a normal complication?! and hopefully not uterine problems!!! HELP! PLEASE!
