forgot to take 2 birth control pills

I started taking birth control pill on 03/19. I usually take the pill at 9 am. I forgot to take the pill on 03/25 and 03/26, so I took them both at 4 pm on 03/26 along with planB pill. I have a sex in that morning.  My last period was around 03/15-03/18. I also had a sex on 03/18 and 03/20.  Do I have possibility to be pregnant?

Morning after pill is not 100% effective but sounds like you're as safe as you can get.  Most women are not fertile just a few days after their period anyway, many women take several months to be able to conceive after stopping birth control pills and 2 pills + morning after pill is a lot of hormones all at once.  I wouldn't worry about it unless you miss your period, but if you are still stressed you can always take a pregnancy test when it has been long enough to put your mind at ease.
