can it really happen?

So my fiance and I have been trying for two months for a baby.. I'm two days late and last night I started feeling almost nauseous like an upset stomach kind of feeling. still feeling it this morning.. My fiance got laid off this week on his job, he has a temporary job for 3 weeks but still is stressful.. ive wanted to become a mom my whole life. I'm hopefull some but not getting my hopes up.. ive never felt this feeling in my stomach before so idk what's going on!

any ideas or suggestions??
