So I am 11 days late for my period. I've taken like 6-7 blue dye test and they all have faint lines but noticeable and seem to be getting a little darker each time. However I took 3 pink dye and they were all negative. I'm so confused and I'm starting to lose hope in being pregnant. Has this happened to anyone else. I have an ultrasound tomorrow to look at my ovaries. I'm praying they see something that can shed some light. Any advice.
