Ttc but upcoming endo surgery

Kamryn

Hello ladies! So I was due to have a laparoscopic surgery Friday but doc had to reschedule (not sure when yet, I will find out tomorrow)

Well my husband and I have been trying for a baby and turns out today is ovulation day! I was just wondering how soon I could get a positive blood pregnancy test. I will be having pre op labs done before surgery so I would like to know how soon it could be detected.
