Trying to conceive, please help?!?

Hi, I am 22 years old and my husband and I are TTC. I my period is scheduled to start tomorrow or the next day. I have had some symptoms (but it could just be PMS.) I just took a home pregnancy test, I could swear i seen a very faint line ( or maybe my mind is playing tricks on me) it was so faint that i couldn't tell for sure. I am going to retest tomorrow and Saturday. Has anyone else had this happen before? Is it to early to test? Am i getting my hopes up?
