You could very well be pregnant. The only way to tell is either take a home pregnancy test or make an appt with your doctor for blood work.
This is my first pregnancy and I didn't have any implantation bleeding, so im not sure what it looks like or how light/heavy it should be. But my breast did swell and become very, very sore right away ( I tested when I was 3 days late).
when you take any kind of medicine while on the pill, the meds can possibly throw the effect of the birth control pill off.. you could have very well conceived while taking your b/c pill and the meds from being sick. Either take a HPT or make an appt to see your doctor to find out for sure.View Thread
