HELP HELP

So I am on my 7th day of ovulation, on Saturday 5th day of ovulation, I had some pinkish/brown spotting and then today I come home from work to go pee and I have burning and can not go( I will be calling my doctor in the morning) I haven't had any issues going all day. My periods are irregular so I never really am sure when I ovulate, I'm not due to start until the 31st... Any suggestions?????
