2 weeks and still waiting. Fingers crossed

This is my second clomid cycle. Last cycle my usually very long irregular cycle was 27 days. I believe it was bc of the clomid helping me ovulate on time. My period came exactly 14 days after I ovulated. This month, I took the clomid days 5-9. Had sex everyday from cd 9-16 (doctor recommended sex every day between cd 12-16). This month I really was not stressing but or ovulation tests bc i find myself getting really stressed out and obsessing over it. I just wanted to take it easy this cycle, TTC has been staring to feel like a job since we have been trying for over a year. So I believe I ovulated cd 15 (based off of my cm). It is now cd 30 and my boobs and nips hurt when I touch them, for about a week now. Usually about 2 or 3 days b4 AF they hurt on the sides only and I will start spotting for a day then they stop hurting and AF comes. This time around the first day of my boob pain i noticed my nipples were sore and I was so nauseated that I could barely keep food down that day. The nausea went away but my boobs are still sore and no spotting or any sign of a period. AF should have came yesterday and nothing. I tested 2 days ago and bfn. Also today we had sex and I got some really bad cramps. that never happens. I have been getting very slight cramps that come and go randomly. what do y'all think? I don't want to get my hopes up but I think this might be it! My last 2 pregnancies did not end well. One ended in miscarriage and the other was an ectopic and my tube went with that one. Although I really want this to be a BFP, I am petrified to even mention anything to anyone including DH until I am absolutely positive that I am. I have one test sitting in my study and he doesn't even know I have it. When do you think I should test? Do you guys think I'm having symptoms or is it all in my head?
