Ovulating 2 weeks after chemical?

Is it normal to ovulate two weeks after a chemical? Got a positive pregnancy test on 8/11- started bleeding on 8/20 but only bled for 4 days? pregnancy tests have been negative and hcg test was only a 13 on the 19th. Been tracking with OPKS since I stopped bleeding on 8/24- they have been negative until tonight at 1130pm I got a positive 1.42. Tested again at 220am just to see if it was darker and it was a 1.94!! So I’m definitely ovulating. We’ve been having sex since I stopped bleeding- drs said we could immediately start trying again. (I was only about 5 weeks)

Praying we get pregnant again this month and it’s successful but I’m so nervous! 🙏🏻❤️
