Am I pregnant?

My husband and I have been trying to conceive for 4 months now. My periods have always been pretty normal. I'm almost two weeks late and still get bfn's. I've been tracking my fertility since we started conceiving with the Clear blue digital opk. I've been having twinges, cramps, and weird pains on each ovary every once in a while. My boons have been super sore, I get dizzy, and I've had headaches every now and then in the middle of the night. I haven't kept track of frequent urination but everything else seems different. It's been going on for a while now. What should I do? Anyone else got bfp's after being real late?
