2 positive ovulation tests in 4 days...so confused?!

April

hi everyone. My husband and I have been ttc for 5 months now. I have not had my period since October 2017 so I have lost track of when I am supposed to ovulate. I started using ovulation tests this month. I took 1 on Feb 26th and it was positive, I took one on Feb 27th and it was negative. So I decided to take another one this morning and it was also positive. Please help!! I'm so confused.
