Sonoline fetal Doppler

I am two months late going on three. I have taken many tests am and pm. I have way too many symptoms to just let it pass. Headaches, neasea, ALWAYS TIRED, my nipples have gotten darker, breasts fuller, and of course the missed periods. We finally decided to dry a Doppler since I do not have insurance yet. I keep picking something up about 120 and has shown as high as 140. Nothing clear with sound though. I have also heard something that almost a resembles a loud whistling wind on my right side by the pubic hair line and hip. I don't know if this is actually something or me thinking it is. Any words of advice, I am stressing way too much and have no clue where to turn.
