I'm pregnant! Only 4 weeks but I'm so excited and need to tell someone!

My husband and I are incredibly thankful and grateful to get pregnant so quickly. We didn't think it'd happen so fast. I was on birth control pills for 13 years and stopped in March. I bought six packs of dollar store tests and two expensive digital ones. I tested on DPO 11 in the evening just because I was excited and wanted to practice peeing on a stick. One solid and one faint line. I tested the next morning and again had one solid and one slightly darker than before line. I waited till this morning to test again and I got two dark lines. I tested with the digital one and it said I was 2-3 weeks pregnant (I hear you're supposed to add 2 weeks, right??).

Can I be excited and happy? Is it too early? My doctor's appointment is next Friday and I hope everything goes well. Can I finally stop lurking and join you guys in this sub?? I'm so happy this is happening but nervous that somehow I'm wrong and not pregnant.

Just needed to spill this out!!!! Thanks for listening :).
