Quick question!

Samantha
Just found out last friday that I am pregnant. But to be honest, I feel like I'm further along than just 5 weeks. I do not know how soon you feel tired during pregnancy bc with my first child i didnt know i was pregnant until i was 12 weeks. This whole past month i have been exhausted, and i mean from the time of my last "period" to now. My last "period" was only two days and very light, not a light flow but not spotting either. I tried calling my dr and telling them my concerns and they won't bring me in to check or anything to see how far i am. Do you think im just over thinking things?
