Has anyone ever gotten pregnant while using the pill? Also, how soon after getting pregnant did you begin to notice symptoms?  My period ended ten days ago and I took a test last night and it said negative but I've been experiencing symptoms for the last three days now and I'm just curious if anyone else has ever experienced this before? I've been back on the pill a couple of months now and I haven't missed a day taking it but if it happened to fail, I sure wouldn't want to continue taking it. Any input on this?
