I started taking the Yaz contraceptive pill and soon after heard many bad things about it. This has played on my mind a fair bit and don t feel comfortable using it. So after 3 days I stopped taking Yaz and now taking Estelle (Juliet) which I ve used for many years previous. Today I feel really tired, my left arm feels weak and I feel nauseaus. I usually feel sick after taking the first couple active pills, but my left arm is worrying me. I don t have any other symptoms, other than the tiredness. Should I have gone from one pill to the other?
