Blood work. Please advise

Al

I went in today to get my confirmed pregnancy through blood work with my fertility dr. They’ve just called and gave me my beta numbers/progesterone level and she said they were all wonderful. Now they are wanting me to come back in AGAIN on Monday for more blood work to check the levels. She said it was normal, but I couldn’t help but feeling like something may not be quite right for so much needed. Has anyone else experienced this??
