Am I pregnant?

I had my ovulation on 1st or 2nd march. AF was due yesterday 14th march( CD28). I am a day late. Had period like cramp yeaterday and have been spotting for 10 days now. Sore Boobs on and off. Apart from spotting that started 5 dpo( very little on wiping however turned dark brown since the past two days but on wiping) and sore boobs and cramping on and off nothing else that i feel...i am too scared to see a BFN so not testing for another two days... what do you guys make out of this?
