I really dont understand!

So I had positive opks all day yesterday, both urine and saliva. My saliva one is still positive today and im pretty sure my urine one is also. I was all excited coz I thought this is it yep im def gonna know that im ovulating! Then I got some brown spotting. So I wrote on here and got some advice and yep I put it down to ovulation bleeding. Now my brown spotting has turned to pink/red. Almost like af is coming. No cramps tho. Please tell me im not getting af on cye day 13 (I think)!!!!!!! My last af was my usual 4 days. I am sick with the flu & ill tell u bding last night was like running a marathon!!!!! Help please!!
