With my first I didn't know Iwas pregnant untill I was 5 weeks along so that took out the anxiety out of finding out. Even though all the signs were there, I slept until 11am, almost fainted several times, my period gone for a week, I never thought I could be pregnant. It was a huge surprise.
Now, my second pregnancy was planned and it was soooo stressful checking every month for symptoms, feeling pregnant but I wasn't it took me 6 months to conceive and strangely enough that month I thought I wasn't pregnant since I had no symptoms at all. I had wasted so much money on pregnancy tests that I thought "here's goes nothing again" and it turns out I was pregnant. I tested two days prior to my period and the two lines were clearly there (yay!).
I started feeling extremely nauseous when I was 8 weeks along so for the first two months I had no symptoms at all. every pregnancy is so different, also there are tests now that can find the pregnancy hormone even 6 days before so hopefully you will be able to test soon to find out,
good luck, I'll cross my fingers for you!
