Paranoid!?

We've been trying for over 4 years, every month was like whomp whomp, failed again :( then on Easter Sunday it was day 28 with no spotting, and i thought what the heck? And BFP!! but now I'm absolutely paranoid that something will go wrong because we have wanted this for so long...I bought a whole bunch more pregnancy tests just to re-assure myself, 6wk 5d and still no symptoms, anyone else experience this? This is my first so i have nothing to compare to, no clue what to expect, maybe I'm just crazy!
