My husband and I have been ttc for a little over a year

My husband and I have been ttc for a little over a year. We decided to go see a fertility doctor. We went to the doctor for a consult, he went over what to expect and what is needed from me. He ordered tests such as the hystersalpingogram and sonohysterogram. I was suppose to call the very first day of my period to schedule the tests, which was about 2 weeks later on March 27th. I never got my period! Glow alerted me that I was on day 2 on my period but there was no period. I took a home pregnancy test on March 28th and a very faint line came up. I didn't believe it and was in shock. I showed it to my husband who didn't believe it either. I took another and another and another. The next morning I took a different brand and that to was positive! I went to the doctor and they did a urine test which was also positive and a blood test to confirm it. The results came back yesterday and my HCG levels are right were they are suppose to be for where I am at in my pregnancy! 5 weeks today!
