Pregnancy Symptoms While Breastfeeding?

I have been breastfeeding my daughter for almost 11 months. I think I might be pregnant, but do not know how to distinguish the differences since my hormones are not back to normal. I have been visited by AF since 8 weeks postpartum, lasting 8-11 days. My last  few cycles are back to the normal 5-7 days. I had 2 positive ovulation tests this cycle. (Taken same day) My husband and I ttc prior and during ovulation.
