Question.

So I thought I was pregnant but I've been getting negative tests. Last week I took an ovulation test because my calendar said that's when I was supposed to. I didn't have any signs that I was but I got a dark positive one day and dark postive the next. Now a week later my boobs are even more swollen and I had stringy mucus like discharge and my temp right now is 99.1... What does all this mean, I'm confused..
