Vomiting and nausea symptoms and conditions

I have been taking Femcon FE for one month. I am on my inactive week and I have had breakthrough bleeding during week 2 and week 3 and now I am bleeding extremely heavy. I used a super kotex tampon AND an always super overnight pad as a backup and bled through the tampon in 1 hour at the worst of the heaviness. I had some vomiting and nausea the first week but after that the only thing I noticed is mild breast tenderness and my legs are cramping at night. I called the GYN and they said to stick with it until the 3 months are over. I had to leave work today to come home and lay down because I was bleeding so badly. I'm not sure if I should continue to take this or not. I have had irregular periods and had extended bleeding which was light but would last for 3 weeks at a time.

20 min after my second dose I experienced severe vomiting. Headache, vomiting and nausea continued for 32 hours – I could not hold down more than a sip of lemon/lime soda or jello. During that time I my skin became itchy, the next I developed a rash on my neck and chest... I have been taking hydroxyzine, which relieves the itch, but a month later the rash persists…
