7 days in a row with positive OPKS!!!! 🤨

Hey ladies , so i started testing for opk last week, it was very faint until a few days later I got my dark thick 2 lines (POSITIVE) since then up until this day (4/12/18) I’ve been getting positives! I’ve been with come and go symptoms such as Headache, Light Cramping, Sore Nipples, exhausted, urinating more than usual with a creamy discharge that started yesterday (4/11/18) this has never happened to me before , I’m really confused! I did some research and some say that opks can pick up HCG before the actual hcg test can, but I took 2 HCG test yesterday and both negative! Help ????!!!!!!
