Is this true

JM • 28 started TTC #baby 1 June 2016. 2 and half years 🌟
App tells me implantation is today I'm 9dpo, is that correct? 
I've had a sick feeling in my stomach 
I've got heart burn/ indigestion, and I keep burping. 
Is implantation on the 9th day after Ovulation? As I ovulated on the 22nd. 
Need a little help
