Tmi maybe but help!!!!

💖Amanda • Have a 5 year old from my previous relationship. Now married to my true love and baby #2 is due aug 2015
So last night after using the restroom I saw mucus in a round ball like shape almost. It was about the size of a small grape. I've never experienced that and I'm only 9 weeks.... Could I have lost my mucus plug already???? This is my second pregnancy and we've tried for so long I don't want to have a miscarriage.
