Help??

Louise

I'm 2 days late on my period and 3 days after I ovulated this month I had a day of brown discharge but I've had nothing since. I've had really bad back ache and hip cramps for the last week and today I had some stringy clear discharge which I'm a bit confused as I normally get it when I'm ovulating. Could this mean I may be pregnant? We've been trying to conceive for about 6months.
