Metformin and clomid

Ashleigh • Married to my best friend. We have a 6 year old son, 1 miscarriage and currently ttc our rainbow baby 🌈👶🏻
Any success stories out there? I would love to hear them. I'll be starting my third round of clomid soon (50mg, 100mg now 150mg). Still no ovulation. I have a sonogram to determine if I have pcos on the 25th of this month. Starting to get discouraged. Send positive vibes my way please.
