Can someone PLEASE give me some input?

I have never really had an issue getting pregnant before getting my tubes tied so this logging and dpo stuff has me all confused. I have 2 apps, one says I'd ovulate on August 9th, one says the 14th. We've been bd all month. Tuesday I started cramping, yesterday I had a tiny bit of spotting when I wiped. When we went to bed last night I was hit heartburn and nausea. Today I've thrown up twice. When could I take a pg test? I've attached a picture of my log because I know temp can indicate ovulation. Thank you in advance!
