I'm a 24yr old active woman.. My boyfriend and I have been having sex but we do the withdrawal method.. For the past 2 months I've been spotting for 2-3 days instead of a normal period... I'm not on b/c because I choose not to be but now for the past couple of days, I'm sweating, light headed, I threw up liquid twice today, I'm tired all the time, I have no energy, and I haven't been able to eat so I have to force feed myself. I need help because I need to know what's up.
