CB digi question!

Karli
Alright ladies!! I'm freaking out over here!! When I first got my bfp I used a cb digi with weeks estimator. It said pregnant with 1-2 weeks.
Well a week later I took another and it still said 1-2 weeks.. I'm freaking out!! I had a blighted ovum in January and I'm terrified that it will happen again and since the weeks estimator thing didn't change in really worried! And to make matters worse my husband told me last night that if this pregnancy doesn't stick we are done and he's getting snipped because he doesn't want me going through pain of mc again and there's "obviously something wrong with one of us."
So on top of being freaked out that I may mc again now I'm scared that this is really my LAST CHANCE... Any advice??
