Hey Jengrace84, I can sympathize with you.
I am currently 5 weeks and 6 days and I have an early scan this Friday.
In the beginning, I was nauseous and my breast were completely sore, today? I even question if I am pregnant. I have no symptoms, regarding nausea and soreness. I feel like they all disappeared.
My mind is racing and in hopes everything will turn out okay this upcoming Friday. I feel like this early scan will definitely put my mind at ease and allow me to feel comfortable to let close family members know, if all turns out well (as of now, only my self and my OH are aware of the pregnancy).
I did have some heavy cramping yesterday (no blood) which did not help with my stress levels but my OBGYN did say that it is completely normal to feel pregnant one day and not the next. Also, cramping is normal in early pregnancy.
I have heard many successful stories of women who had experience this early on and went on to have a full term pregnancies.
Maybe it is just the motherly instinct in us to worry! ha
Sending positivity your way, since it does us no good to worry so much.
