Hello, I've had my implanon removed April 15 of this year, I've had unprotected sex for at least 4days and he came inside me all those times. Lately I've been having some symptoms of always being tired but restless nights, peeing a lot, heavier and sore breasts, lower abdomen cramps/pain, low back pains, movements in my stomach area? Also small minor headaches and no period in the past month not a single drop.. i took an HPT a week after having sex but they both turned negative.. Could I be pregnant ?
