Bleeding during ovulation.

My period ended December 21st ..so according to my chart im ovulating..but this months ovulation is way differnet then any other ever. Typically my nipples hurt like crazy when ovulating but not this month....also i have been crying alot ...and not been feeling so good to my stomach....and now...there is blood everytime i wipe..like fresh blood sometimes more then others..this has been going on for two days. What is going in?? Can u have a period and still be pregnant? Should i test??
