birth control
"I had Nexplanon in for a year and 3 months. Before inserting the implant, take the mini-pill which is progestrin only (just like Nexplanon) that way you'll know if you can handle the progestin-only effects. Most bc pills that the majority of us start off with are a combination of estrogen and progestin, the mini pill and implant have no estrogen to be more marketable since a lot of women are allergic to estrogen. On the implant I did not have periods, just spotted when I was stressed which I loved. I gained 29 lbs which I did not love. I was nauseous and constantly felt dehydrated. The body thinks its pregnant so you definitely feel "off." I didn't gain any weight on the combo pill- not looking forward to taking a pill everyday again."
