4th Round of Clomid now at 150mg

Hello ladies! Anyone have any success stories from being on 150mg of clomid? I really thought the 100mg was going to work last month but AF showed her face once again! I’m gettin extremely frustrated and it’s sooo hard to stay positive during this journey! My hubby has been very positive but for me it’s really hard. We have been ttc for 14 months now. I just found out another one of my friends is pregnant and they don’t want kids but are deciding to keep the baby! Of course all of us women on here would give our left arm to be pregnant! I don’t understand. Need some positivity sent my way!
