Implantation bleeding?

Cassandra
Hi ladies,
 I don't want to get ahead of myself, but I started to bleed today. This would be early for a period. I am on 100mg clomid and this is my 4th round and I've had pretty low progesterone levels but increasing the dosage last month helped. The blood appears to be very pale/pink with clear fluid. Just wondering if this is what anyone else has looked liked. I took a pg test yesterday and it was negative. My ovulation peak was taken on a home test on October 16th and my period wasnt due until the 30th. I don't want to give my hopes up but I'd like your input!
