Hi everyone, this is my first time posting here. I hope I can get some advise.

My husband and I have been trying to get pregnant for a year. And it hasn’t happened. I got my period March 7th, and was expecting to get it April 5th. I took a clinical guard pregnancy test and it showed a very faint line which has never happened to me so I got really excited and to make sure I went to buy a Clearblue digital test. I took the test and it said PREGNANT! I was so excited and have been thinking all day on how to surprise my husband when he gets home. But me being the way I am, I had to be extra extra sure so I took another Clearblue test (same day) a little over 2 hours apart and it said NOT PREGNANT. This got me so disappointed.

Does anybody know why this could’ve happened? Is there a chance the last test could be wrong?
