My husband and I have only been trying for 2 months

My husband and I have only been trying for 2 months!! I took a pregnancy test because my period was late and it was very very faintly positive, I almost thought I had imagined the line lol. Took a couple more over the next couple of day, still a faint line. Then I took a digital test and it can out negative. I was so frustrated and really just wanted to know if I was or not so I called my OB office and asked for a blood test to know for sure. Results came back POSITIVE!!! She said my levels were pretty low still so only about 4 weeks along. Expecting our little one in July!!
