Could this be a side effect of birth control?
I started the pill 3 days ago. Yesterday something funny happened. I got lightheaded, weak, and short of breath, until it reached the point that all I could do was lie in bed. Today I am feeling stronger, but I still cannot stand for very long until I am too weak and short on breath, and my heart is kind of pounding, the way it does after I've had a strong cup of coffee. (I'm very sensitive to caffeine.)
Starting today I've had wild mood swings all day long, which I expected. So I know that at least is probably the birth control. Could the pounding heart and weakness be a side effect? If it is, is it safe? Normal? I'm 23, and doctors have given me a clean bill of health. I know the safest thing to do would be to call my doctor, but I can't afford that, so at least I'd like to hear some stories of how the pill has reacted to others.
