I have missed my period completely more than two weeks ago. I am on birth control and have been on it for 5 years so I am not a new user. I accidently missed the Friday pill on my third week on my last pack, then the following week was when I missed my period. I have been feeling really tired, have slight cramping, head aches, and my heart rate is in the high 80's/low 90's. I took a pregnancy test a week after missed period, it was negative? So anyone have this experience or have any insight? I think I may be pregnant but I'm not feeling the other symptoms such as sore breasts, throwing up, or hardened stomach. I am so confused. haha.
