Okay .. I had the nexplanon implant removed on February 8th 2016. My first period after that was March 16th-19th. SO and I had sex every few days from March 20th and on.. The difficult part is before I was on the nexplanon implant my cycles were about 38 days. I am now on day 40 so I am wondering if this is normal because of coming off if the nexplanon or if I should test for BFP! Any advice is welcome, thanks !
