Need words of encouragement

So my last cycle was in February. I didn't get one in March so I took a pregnancy test and it was negative. This month I took a test and it came out positive. Went in today for a blood test and it came back positive for early pregnancy. I don't know how to feel about this because I have no idea when I ovulated or how far along I am. I have to go back to the doctor Monday for another blood test so they can check my hcg levels. I don't feel pregnant except, always tired, sore nipples, and nausea here and there. But nothing major. Anyone been through this???
