Clomid and trigger shot next cycle

Krystle • Mother of 3 boys one 6 year old and 2 month old twin boys
I will be starting 50mg Clomid next cycle and getting a trigger shot if my follies are 18mm on cd14. We have been ttc for 18 months now and we have tried losing weight and metformin 1500mg but I still having really long cycles hoping to actually ovulate next cycle.
