I'm in shock!!

So I thought for sure I was out of the game this month.. AF due today and I honestly felt like she was gracing me with her presence. I took several hpt's and they were negative. I went and had some routine blood drawn yesterday and today the nurse called and said my blood work tested positive! I'm excited but shocked. My question for everyone.. Is it ok to start exercising after just finding out? I started a couch to 5k routine to try and be more healthy and would still like to try it. Opinions???
