Ovulation, is this normal?

Lovely • IG: MakingBabyDay TTC #4. Sept 2014 tubal reversal. Feb 2016 HSG: blocked tubes. May 2016 IVF: failed. Aug 2016 BFP turned to 4th loss
I had my period twice last month, I'm assuming because my body is out of whack since I had a tubal ligation reversal in September, but is ovulating for 6 to 7 days normal? Did I just throw the app off by having two periods in a month
