Hi Ladies! 
I just got my beta test done this morning - we're pregnant!!! 
After almost 3 years of dealing with I fertility, and 1 m/c I'm November of last year, we have our second chance!!! 
I actually had my beta a day earlier than the two weeks, and my number was higher than back in November and my pregnancy symptoms are MUCH stronger! 
Just curious what everyone's first beta levels were, and if anyone knows whether different clinics have different ways of measuring it!? Everyone I read about ladies beta levels, their in the hundred (like 300/400+). Mine are definitely not that high! 
Guess I'm just nervous and scared as I really hope this is a nice sticky babe!!
