Ortho Tri-Cyclen

I've been taking this form of BC for a week and 2 days, I've had a consistent headache for almost 4 days now, Saturday it got worse and turned into a migraine. Today (Sunday) I felt horrible, head throbbing, nausea, weak, random muscle contractions everywhere etc.  a little while ago, about 1:00 am, I got so nauseous, went to the bathroom and threw up 3 times within 5 mins. Also, have had slight weight gain and breast tenderness, and possible getting bigger, could be swelling. I don't know.
Has anyone else been on this and had symptoms similar to this, or am I just crazy? Thank you!!
