Hi I’ve asked the question before but didn’t get a response. Maybe I made it too long! I’ll shorten it. I am 5’5 and weight around 340. When I got the implant 1.5yrs ago I was smaller. Now that I’m much bigger does it still work? I heard it may be less effective in obese women. I usually have spotting sometimes but recently I spotted for a week and I wasn’t sure if that was normal or not or if it’s a sign the birth control isn’t working. Any help would be appreciated!
