Ive been on the implant since july 6th,i bled for 3 weeks,one heavy,2 light, i wasnt on my period when i had it inserted(6weeks after having my baby) i didnt get my period after having my baby. I had sex with out additional method 2 weeks after insertion but im worried as alot of people bleed up to 3 months non stop and i stopped after 3weeks! Could i be pregnant?
