Pregnant while husbands deployed!?

So these are the tests

Anyway my husbands going to be deployed for a good majority of this pregnancy. I’m currently 4weeks2 days pregnant. And idk but I had a chemical in December

Would a chemical make a digital test come back positive?

Obvs my lines are getting darker (these are cheapy hcg tests so.

Sorry just trying not to worry 💗💗
