Nexplanon question!

Hi ladies, so I know that nexplanon is different for everyone but I have two questions. 1. Has anyone here gotten pregnant while it was in your arm and 2. What are y'alls periods like with it? This is probably my 3rd month with it. The first month I just spotted and the next it was a normal period (maybe a little shorter). Also my husband and I just got married and I just started having sex. Point is I'm a bundle of nerves about getting pregnant or how aunt flo will show up this month!
