### input:
I went on continuous birth control (combined pill) around 4-5 months ago instead of taking the regular 21 day off 7 day style.  I still have breakthrough bleeding every month during when my period is supposed to be, but I just continue taking the pill and it eventually goes away.  But this last month, I had a period for 3 weeks.  I called my gynecologist and she said to stop taking the pills for 2 days and then get back on them and stay on them.  I stopped the pills for 2 days and had heavier bleeding.  I started the pills back up and have been on them since.  I asked her how long I had to use a second type of protection.  She said that they tell everyone 1 month, but that most doctors say 2 weeks.  She said to do a month because my body was all messed up and she didnt know where I was at in my cycle.  The thing is I am going to Mexico this weekend and next week and was looking forward to unprotected sex with my boyfriend.  So, I only didnt take the pills 2 days and that was just to have a real period.  I have been back on the pill for 11 days and will be back on it 14 by the time I have unprotected sex.  All the research I did stated I am safe after 7 days of taking the pill and shouldnt worry, but I wanted to know if that was true and why only 7 days.  What if I had ovulated?  Thank you so much for your help!

Thank you posting in Chat Doctor, first of all the pills you are having prevents pregnancy mainly by inhibiting ovulation. If you have the pill continuously your chance of getting pregnant is very less i.e 0.3%. However if you stop having the pill or miss the pill in between you have to have an extra protection like a condom. Since you are on the pill since 14 days, after which you are planning on unprotected intercourse, it is highly unlikely of getting pregnant. However, to be on the safer side you can use a condom.
