Testing question! Blood v. urine

Sarah • 28. Dallas TX. Married for 4 years. TTC baby #1 with PCOS.

My doctor is having me come in for bloodwork tomorrow to see if I am pregnant. I was on follistim and a trigger shot. I ovulated on 3/22.

If she has me coming in for bloodwork, does that mean that urine tests would come up negative? This is the first cycle I’ve even had a chance. I’m nervous! I took a test today and it appears negative, possibly a vvvvfl. Any help is appreciated.
