I have been taking loestrin for over a year. I missed one pill in the middle of week 3. I took 2 pills the next day (one in the morning and one at my usual time). I had my period and started taking a new pack of pills. I few days into the new pack I had sex with my boyfriend and the condom fell off. About a week later I developed a yeast infection, which I've never had before and some people seem to think is an early sign of pregnancy. I went to the doctor a few days ago (about ten days after the condom fell off) and she did a urine test that came back negative but I'm still really worried because maybe its still too early to show on the test. Please help I'm freaking out.
