Hello,

i'm in quite a dilemma. You see, I am currently on this brand of bcp of 21 days, however, i've lost one pill, so i'm stuck with 20 pills, and do not have any current supply of the current bcp i'm taking. However, i'm thinking of switching to brand b of birth control pills, and i'm not sure when to take the new batch of this new brand. My 21 pills usually end on wednesday, and I would allow 7 days for my period to come, and I would continue on on the following thursday.

Do i, just eat the 20 pills until wednesday, and stop for 8 days instead of 7 days, and continue with a new brand of birth control pills on the following thursday? Or do I start counting from wednesday (with only taking in 20 pills instead of 21), and then start a new brand of birth control pills on the following tuesday?

What do I do? Please advise.
