TTC after years of Birth control

Arita
After more than 5 years on BC and having no period,my husband and I decided it's time. I started taking folic acid pills and other prenatal pills a month or 2 before I removed my nexplenon. I removed it early August and had a period early september. We BD this month during my fertile days and on ovulation day. Is it a high percentage I'll get pregnant,even after just being off BC for a month and a half? I've even started liquid geritol. Help please!!
