March 21

My last period was March 21, Period was supposedly due April 17 (Glows predictions are pretty accurate with me) and i am Normal. Never missed a period before, Been TTC 9 months now, Taken one test and it looks positive BUT it was blue dye and it was hours later i looked at it, Took another one same day and it said "Negative" - Digital Clear Blue test. Both of these tests were May 3rd..... so i waited until this morning (5/14/17) and took one of those 88 cent ones (red dye) from walmart and it's straight up negative....

Has anyone been pregnant and you just couldn't get a positive test with the urine tests but went to doctors and got a positive blood work?

I am NOT stressed, I am feeling completely fine, Nothing i can see to cause the missed period.... and like I've said, I've NEVER been late like this before, only like a day/two off never weeks and weeks on end.
