I am on yasmin and close to a month ago a yellow pill fell out of the container, and i took the next yellow pill instead not realizing that the other yellow pill that fell out was missing, i didnt look at the date i just took the next one instead. I realized when i was on the sugar pills that there was a yellow pill in my bag that i didnt take so i took it while i was on my period, my period shortened but continued and then i carried on with the next pack of pills. I had sex while i was on the second yellow pill of the new pack. They say that birth control only really makes you gain 1 or 2 pounds, but ive gained 10. I always feel bloated and im afarid i could be pregant. My breasts are sore and tender, they ache and have been for two days. Sometimes i have abdonminal pain but its not all that noticeable. I feel fatter, i was so use to being a skinny kid that im not use to this ten extra pounds,im afarid i wont be able to tell if i get my period because its not an actual period. help!
