Everything was fine until.......

I am so confused and lost at this point. I’m just going to insert some pictures of all the hpt I’ve taken over the past month along with the times and dates and tell me your opinions. My doctor have finally agreed to let me come in for a blood test but that won’t be for a few days but now I’m not sure if I can depend on that either... why is my body so difficult? My last period was in the end of January/ beginning of February and is now well over a month late. I’ve had some mild symptoms on and off. I had my follow up appointment today and the last picture is the test I took an hour before and I told my self if these came out negative I’ll just rule it as I’m not pregnant and move on but out of no where it came up pregnant again after all these negatives. Ive been looking into cryptic pregnancies and wonder how would they be able to confirm that if it’s nearly impossible to detect.
