13 dpo and i see this. This is my 3rd pregnancy this year. The first one ended in a miscarriage, the second in a chemical. My husband was diagnosed with type 2 diabetes a month ago and we have reason to believe the diabetes played a role in our losses. There is scientific evidence that untreated high blood sugar in men can lead to sperm with unhealthy, deformed DNA. He started on diabetic medication roughly a little over 2 weeks ago. I’m cautiously optimistic.
