Nervous/frustrated

After missing my period this month on month 4 of TTC.. I went to my obgyn and she took bloodwork for hcg & thyroid.. Both normal. Send me for a transvaginal ultrasound which I have to wait a whole WEEK for results to make sure everything is ok. Ultrasound tech mentioned a possible cyst on my right ovary but now I'm worried about the other options of what she was seeing.. Help my nerves are shot!
