Holy Blood!

Sooo....I'm currently 9 dpo. Last night, I was feeling little twinges in my pelvic area. Went to the bathroom, and bright red blood just gushes out! But that's it. I usually have very painful and 5-7 days of bleeding. Since the one episode last night, I've had no period symptoms. No more blood. The thing is, this is the first time I'm using progesterone to lengthen my luteal Phase. So I stopped taking it for about 16 hours because I thought my period had started. After consulting 3 separate friends who have been on progesterone, the consensus was that I should continue taking it since this doesn't seem like a real period just in case. What do you guys think? Has anything similar ever happened to any of you and you still ended up being pregnant?
