BFP! So excited but...

My husband and I have been trying for over a year and we finally got our first BFP!! We could not be more happy and excited but we are both nervous about getting our hopes up. And I have done exactly what you're not supposed to do...I have googled everything! So, I have basically taken 1-2 pregnancy tests a day...crazy I know! But I'm nervous that it's too good to be true. I think I'm only about 4 weeks and my confirmation appointment isn't until March 8 (how am I going to wait that long?!?). And pregnancy tests are not cheap! Anyone else felt this way?
