So I'm on my first round of clomid & I was supposed to go for my 21 day blood test at my doctors on Friday. When I arrived they told me I was 20 mins late for my app, I booked it for 5:10, I was there at 5:10, they tried to tell me my app was 4:50, it wasn't. Anyway, they then said that the person who takes the bloods to the local hospital left at 5 so they wouldn't do my blood test. I call my fertility clinic to ask what to do but they don't answer (left a message, had no response). Should I book in for a blood test on Monday even though my day 21 would have fallen on Sat??
