Hi ladies! I took a short break from TTC but now I'm ready to continue my journey! I did 4 rounds of clomid that were unsuccessful and now I'm starting my first round with letrozole 2.5mg, cd 3-7, I hope this one works!! I have also recently lost 15lbs, I know thats not much but i hear women talk about losing weight to get pregnant, it's worth a shot lol. Anyone have any success stories or suggestions or what to expect with letrozole? I'd love to hear them! STATS: LMP 2-13-17, currently on CD 5, my cycles last between 28 to 32 days long, AF expected around 3-14-17, give or take a few days, ttc for 16 months, no known medical reasons for infertility except for irregular at times, do I got any cycle buddies out there? Trying to stay hopeful 🌈
