Can a girl get some advice?

Audrey

I have never posted on here before but i just couldnt help myself this month. I need some advice. I am typically very regular. I have ovulation pain once a month and start AF on time. I sometimes spot for a day or 2 at most then get my full blown period day 3. This month I felt the ovulation pain twice within 4 days of each other then shooting pain in my right side where I'd consider my ovary. I was supposed to start my period on Wednesday but started lightly spotting Tuesday night. I took a pregnancy test Wednesday afternoon and it was BFN. But I have continued to spot till today and now i havent even worn a tampon all day. I went up in there to check my CM and it was white on the index finger but had some pinkish tone on my middle... Should I take another pregnancy test?
