I started a new birth control a month and a half ago and I spotted for the first month until I started the pills that were suppose to be "period pills" then the spotting completely stopped. I am half way threw my next pack and I have not spotted at all until last night. I stopped taking them 2 days ago. Could I be pregnant? I missed my period and I have realized that my urine has been darker and stronger smelling for about a month now and I have found myself having to urinate a lot more.
