So I'm in birth control and yesterday I forgot to take it so I took it today's hen I realized and then took my normal one at my usual time (7:00pm). I did this in the summer once and I also got sick. I'm just wondering if that's a coincidence or can you throw up from take two in one day?

The increased amount of hormones may be enough to make some women sick, just as some women get sick with their period or as an early symptom of pregnancy. Some people are more sensitive to changes in hormone levels than others.

Agreed, for many women no, it would not, but it is possible that it can.
