Please help me! I cannot take a HPT because it is too soon. I missed the first three pills of my birth control (Sunday - Tuesday). I started taking an antibiotic on Monday. I had sex on Wednesday. I had only taken one BC pill at that point when I should have taken 4 already. Now it's almost a week later and I have been getting dizzy and tired. Is it possible that I am pregnant or is this probably just stress? I have two wait almost two weeks before I can use a HPT. Please help!
