3.5 months PP and pregnant?

Ashley

I am 3.5 months postpartum and my husband and i have been having unprotected sex since 8 weeks when we got the clear. I exclusively breastfeed and am on no birth control. I have not received my period yet but for the past 3 days I've gotten positive ovulation tests. No positive pregnancy tests yet.

Last time I was pregnant it started with a string of positive opks.
