I don't want to jinx it...prego??

  Hubby and I have been trying since our wedding in September 2014. Went to the doctor a month or two ago and all seems normal, told me to get an ovulation kit. Finally found out When I ovulate, did the BD on that day and a few days before that. I'm about 9-10 dpo now with light cramping, extremely tired every day which is not like me, stomach has just been feeling 'upset' since about 3 dpo. More Vivid dreams than usual and wake up feeling like I've slept for 24 hrs. I had one dark red/brown spot on my underwear right after ovulation, possibly on the 2 or 3 dpo. Tested on the 5 or 6 dpo and was negative..too early probably. My af is due on Saturday 6/13.. I don't want to jinx it!!
