Ive reciently tried the nexplanon implant and had major problems. Dizzy spells, passing out, and then seizures. The day i got it removed these symptoms stopped. Yesterday i started taking pills, and today, i had another episode. I hadnt had one when i wasnt on anything. Whats causing this? Has anyone had something similar happen? Any answers? Whats a good alternative to EFFECTIVE birth control? Ive already had one baby, and dont want any more!
