... headaches and severe cramping. In the beginning I had my period for a month straight and I haven't had it since.. but now I am urinating more, I'm more emotional, I have the pains like I have diarrhea but I can not use the bathroom, I smell things before others, I'm craving foods that I normally wouldn't like and I am bleeding very lightly could I be pregnant or is it just the Nexplanon symptoms and where the Nexplanon is it sometimes gets swollen
