trying to conceive

Totally weird! I never really tried to conceive. I have two children whom were both surprises. So I had mirena removed 10/6/16. Hubby and I have been actively TTC since my period ended 10/10/16. I'm experiencing sore breasts, very weird cravings (peanut butter on pickles!), and my bbt is increased steadily, AND my cervix is high and soft. pregnancy tests are coming back negative. Had one positive but it was a blue dye and I know those have a bad rep for evaporation lines. Sorry this is so long. I've never been so confused.   S.O.S
