I'm in shock!!!

Me and my partner have been TTC for about 2 years now, and have had 2 losses. I have PSCO so i always thought it wouldn't happen for us. Anyway, about 3 weeks ago I took a test and there was a very faint line on it, after taking another one I got a negative and put it to the back of my mind! The past few days I've been feeling very tired and not myself so I thought I'd take a test to rule it out and within seconds two bold lines came up! I'm still in shock and I'm shaking lol!
