It depends on the person.. But you really should consult your doctor before you do anything.. he could suggest another alternative for you. I had to try a few times to get the right one for me..
But One of them was totally making me sick and feel horrid.. I had my period, 6 days later refused to take another tablet, and the following day I got my period again, my body was going nuts.
I had a good 2 years, and now I'm off the pill trying to conceive.. but I have good months and I have bad ones. I think it was because I was trying to play doctor, instead of seeking medical advice in the first place.
So please seek medical advice first, just to do whats right for you.
All the best
