Advice please???

Brittany • I`m a 25 year old mommy of 3. Just found out my 4th blessing is on his or her way. ❤
Hey guys. I found out Sunday that I am expecting. According to my LMP I should be 4 weeks and 4 days today. I made an appt and they won't see me until 9 weeks so I sort of fibbed and said my period was the week before to get in a little sooner but it's still not until 11/25. I'm just curious what my levels are. Any suggestions on what I should do? Should I call my primary physician?
