I have regular cycle between 32 to 35 days length and each month I ovulate between CD 18 - CD 21..is this a normal pattern... Last month I was trying to conceive and i had intercourse ever 2 n 3 rd day from CD 12 and then I noticed egg white slippery mucus at CD 22 I took a ovulation test n found that i ovulated that late as the test is beaming strong.. Though I didn't conceived that cycle.. My doctor has given me letrozole for conception but i actually don't have any issue with ovulation or cycle my Tsh is 1.86 and i want to plan again this cycle.. Should I go for letrozole again or should I try it out naturally.. As I thought letrozole has made my hormone system confused as I got 3 times positive opk last cycle...any Advice is really appreciated..
