Two week wait crazy

I'm 40 years-old TTC After a tubal reversal do e April 29th. I don't know what DPO I'm on glow says I ovulated on the 18th but the Flo app says I ovulated on the 20th. Been having mild cramps and back aches for a week now. A little nauseous but not much, Marijuana helps with that (Planning on stopping when I get my positive don't judge me ).Guessing's too soon to test negative pregnancy test day before yesterday. Trying not to test again till the 30th
