I ovulated on 5/10. About 8 days after I had a light pink color when I used the bathroom (on 5/17 and 5/18). After the pink its been bright red like a period for the past two days (5/19 and 5/20). I'm not supposed to get my period until 5/27 and my cycles are always 28-30 days. If this is a period then this cycle would be 20 days. Could this be implantatio blood? It's a lot!

Usually, if someone is going to have implantation bleeding... it's not commonly seen, it is fairly minimal. There are often exceptions in many things to do with pregnancy however. You'll have to wait and see what happens when you normally would have your period. If things seem off, and you feel there is a chance of pregnancy, try a test. Might be pregnancy, might be an off cycle.

Thanks so much! I think it is an off-cycle. Ill be trying to conceive again soon! Its simply too heavy to not be a period. Ill hpt next Wednesday (when my period should have come) but chances are I just had a short cycle and will have to rechart and start my ovulation tests again shortly :) thanks so much for taking the time to answer!
