First positive, 4 weeks 1 day

My husband and I have started trying a few months ago. I usually go through 10 pregnancy tests a cycle (slight exaggeration, but I can’t help it! I do test more than I’d like to admit). However, this time around, I waited until the day my period was supposed to come. It didn’t. And I tested positive. We are over the moon and feel extremely blessed. Unfortunately, I’ve been plagued with nasty thoughts of “what if this doesn’t work out?” It’s still so early for me, but I’ve already fell in love with the cute tiny little blob that’s growing inside of me... any words of advice for a first time positive tester? Thanks, sis
