1,001 tests this month!

So basically based on my LMP I should be approx. 8.5 weeks but I’m sure I ovulated later than “normal” as a 40 day cycle isn’t unheard of for me and I believe I’m 6 weeks. My doctor sent me for a dating ultrasound last week and then couldnt date the pregnancy because it was too early. Now they have sent me for blood work and I’m going to have another ultrasound next week! Has anyone else had a cycle that doesn’t fall under “normal” conditions and have to have a zillion tests? It’s starting to really stress me out! I think I’m right with my calculation but I’m beginning to seriously doubt myself.
