I know how you feel hun! I had a very light period and then nothing for almost two months. I really thought I felt movement, and my breasts got soar.(or atleast I wanted to have these feelings) So I started getting high hopes of being prego. But then my period came and a really sad feeling came over me. I checked with my Dr. too and they did lots of test and they found nothing. She said it could be from stress, or even not getting enough rest. I am 37 now and have been trying for about 4-5 months to get prego., but nothing yet. We are leaving it in Gods hands and if it happens it happens. But we will still keep trying :-).
Don't stress, relax and it will happen when you least expect it. I am sure your blood results will come out fine. Have your periods been off before?
Lots of hugs and again don't worry because that causes stress.
God Bless!!!
