recently I had sex with a condom on and no ejaculation. I had to switch to an off brand name of birth control which is supposed to be the same as my name brand "lutera". When I had sex, it was protected as stated above and it didn't last more than 10 minutes. I missed a pill 2 days before so the day prior I took 2 pills and the night we had sex I took one pill at regular time. I was also on antibiotics for strep that I was recovering from. Like I said, my period is supposed to arrive in a week so I have one more week of active pills and then a week of placebo pills but I have been having mild cramping and a white, mucus/thick  like discharge. I'm not sure if it is because my birth control switched so my hormones are adjusting or what. Please help, thanks a bunch.
