Ttc for 7 months

Diamond

I’ve been trying to convince the last 7 months. I took a test on August 8th that looked negative to me . According to glow I was supposed to start yesterday but all my other apps say 08/12/19 . Could I be pregnant or period coming? Boobs hurt a little and I’ll have a very dull cramp like feeling but nothing like normal. Been super hungry and super sleepy the last week or two.
