Help is there a chance

We had unprotected sex last night and my bf came in me. Afterwards we started discussing if we wanted to take a plan b or chance having another baby. Well we Picked up an ovulation test from the store. It was an equate blue dye test. This is the picture. It claims I’m not near ovulation so we got kind of bummed. Is there anyway I could still possibly ovulate soon and still conceive from that sex?

I’m breastfeeding and have no cycle so I’m not sure where I’m at
