7 pregnancy tests later...

We were using another app basically for natural family planning and trying to hold off on getting pregnant... I realized we may have cut it close, so downloaded this app. This app said it was the day before my most fertile day. Fast forward a couple weeks- I just had a weird feeling, and was two days late. I took three cheapie tests that all said negative (though I didn't follow all directions). Still late. Took four more (better brands this time)(I know, a bit overkill, lol), but they've all come back positive! Dr. appt Monday, but I'm freaking out! I want to surprise my husband, but now I have to freak out internally until I tell him. I mean, we're in our 30s and 'ready' (who is ever ready?), but financially I'm terrified and I'm also just.... Stressed. I was NOT planning this at all! I'm growing a tiny life in me now? Wow! What?!? Anyone else sorta freaking out after you found out?
