ADVICE.

I am in desperate need of advice. I have not had a period since early February, and have been ttc. I have taken two blue dye tests, and they came up positive. I took pink dye tests and they came out negative. So I took a digital. And that came out negative. Should I just give up the hope that I'm pregnant? It's been almost two months since my last period. Please give me anything you would think is happening
