I got the Nexplanon implant on the 22nd of January. I had unprotected sex 2 days later, he pulled out. 5 1/2 days after the implant I had unprotected sex, he finished in me. I took plan b a day and a half later. After the 7 day Mark since getting the implant I’ve regularly had unprotected sex. Since getting the implant, I haven’t had one drop of blood. Nada. About 3 days after insertion I had the faintest pink when wiping, that’s it. Could I be pregnant?
