my story...feedback needed

I'm seriously baffled, my last cycle was Oct 16th and I'm on a 27 day cycle. lasted from Oct 16-21st. a few days later I felt pinching on my right side, some cramps for a few days in a row and I thought AF was going to appear. well here it is, Nov 15th and no signs of AF and doesn't feel like she is going to come. in my gut, heart I totally feel pregnant and even have symptoms BUT negative pregnancy test and a few false positives? We did use conceive plus this cycle, for 5 days in a row and I'm unsure what's going on now days?? Did I ovulate later?? I NEED HELP!! OPINIONS, SIMILAR STORIES..etc. someone please help out.
