CD 13 IUI#3

We went the the RE yesterday on CD13 to check out the growth of the follicles. We usually go around this time and they are on the smaller side. Like 12-16. This time there were 2 mature follicles at 18 and 21.5! I honestly think it has something to do with the HSG. My lining is definitely being affected by the clomid. It was at 6. Luckily, it was triple striped/feather patterned. Needless to say, we triggered sooner than we normally do! We did the trigger shot last night around 9. The insemintation will be around 35-36 hours past trigger at about 8:15-8:30 am tomorrow morning.
