I am on gildess FE 1/20. I am on my third week of the active pills and forgot to take my pill on tuesday. I remembered on wednesday night and took the one for tuesday and when it was time for my regular dose i took that one also. Its thursday and i am spotting. I still have 3 active pills left before i get to the inactive pills. Is this normal? how long should i obstain from having unprotected sex?
