Etonogestrel
"Implanon (etonogestrel) has been replaced by Nexplanon and I had mine inserted last friday. So far I feel fine, no feeling sick like I would have done changing pill, no bloated tummy, no spotting. Everyone reacts different to medicines. I have tried over 15 types of contraceptive combined pills, a few mini pills and they all gave me bad migraines. My doctor has recommended Nexplanon implant as it is not known yet to give migraines. I would rather gain a bit of spot bleeding than have the head pain."
