DH with ED LTTTC

[ScaredToHope]

My DH an I have been ttc on our own for six years. I am always regular with my periods and have had no abnormalities found thus far. My DH however, has type one diabetes and has had ED that has been getting increasingly worse over the last five years. The last two tests we've had done indicate that he has a high mortality rate and deformation of his sperm. We've considered our other options but are highly restricted financially and don't know how we could possibly afford IVF or adoption for that matter.
Saturday brought me to 11 days past due for my period and so I took the first pregnancy test I've done in nearly 2 years. Negative.... As always. Now I'm dealing with the ever fading dream of motherhood and trying to determine what's caused me to miss a period.

Any words of advise would be appreciated!
