So close, and so nervous!?

I had 5 days will I was fertile, ovulating. Have had stomach cramps lower stomach and back, creamy discharge more than normal. Heart burn last 2 days, and just look fuller and can see faint veins thts never been noticed. Expecting my period to come the day after tmrw. So close to knowin if I miss my period. Should I just take a test now? Could it be able to tell? Or should I just wait? Does my symptoms match anyones that has been pregnant tht had symptoms before missed period?
