did the different pill mess up my cylce?

Hi,
Welcome to ehealthforum,
If you have not been sexually active, chances of pregnancy can be ruled out. However if you had been sexually active before getting started on birth control pills (without protection), then chances of pregnancy cannot be ruled out completely (as few women can experience period like bleeding at expected period time during first few months of pregnancy). Wait and watch for your periods. If you do not get your periods within 10 days of expected period dates, or if you get abnormal periods, or if you develop symptoms suggestive of pregnancy, you should consider visiting your gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). If pregnancy gets ruled out, further evaluation would be needed to look for causes like hormonal imbalances, ovarian cysts, PCOD, ovarian suppression, etc. Treatment as appropriate (based on examination findings and investigation results) would be started to help you.
Take care.
