Yay or Nay?

We've been together eight years and jusy recently got married this October. I'm 24 and he's 25. He was diagnosed with bladder cancer and will not be able to reproduce children the natural way once his bladder is removed. We gave it everything we had on the honeymoon. My projected menstruation start date is November 6th. I took a test last night which had a very very very faint lime and one tonight (one with permanant marker) and it seems to be getting darker. These are dollar tree tests I purchased pricier ones tonight that i plan on taking when I wake in the morning. This would answer one of our biggest prayers. What do you ladies think?
