So I had my HSG done on 5/15.. where one tube was blocked and one was super clear .I started taking opks on 5/17 cause I was having cramping.. and glow had my ovulation date as 5/19 but I know could be off .. just looking at my opks in this pic would you all think maybe I had my LH surge a day or two before 5/17 cause see how the line is getting lighter from then... and now experiencing period like cramps .. just not sure when ovulated.
