so frustrated

I've been taking OPKs from the end of my period which was the 24th up until now and I haven't gotten a positive. I've tested in the morning and mid day..still nothing. My period is supposed to start the 10th or few days after that if my cycle stays the same. I have cramps off an on for the past 2 days does feel like period cramps..my cm is very light creamy watery for a few days now. I've been BDing almost every other day since my period stopped. What should I do? It's bugging me ugh
