I'm on my first month of taking birth control and tonight will be my second "sugar pill" I'm not sure which kind of birth control I have but i have purple pills then on the last week they are white. I took them the Sunday of my period and they took 2 weeks to be effective according to my Gynecologist. For about 4 days now each time I pee it smells super strong and nasty. I don't know how to describe it but it's very strong. It's like cold tingly feeling while I pee also. When it's tingly and cold it smells, when it's not it's not so much, 80% of the time it has been smelling. Why is that? Also I have had unprotected sex before my pill was effective. and I'm on my second sugar pill and it looks like im bleeding lightly. It's sorta brown. Is this my period coming from this or could it be implantation bleeding? My period isn't due for another week and I'm usually a 31 day cycle but then again I'm new to the pills which can change things
