Pregnancy tests after BFP

Mandy • 27 and just started trying to conceive. Hoping it happens!
So does anyone else take pregnancy tests after getting their BFP? I keep taking them mainly out of disbelief that I'm actually pregnant. I have my first appointment and uktrasound in May 6th and I think I will feel MUCH better after that once I hear the heartbeat. 
Any advice or similar situations is appreciated! I feel like I'm crazy lol ☺️
