2nd HCG number

So I got my 2nd HCG number on Monday!!! It was a fantastic number of 4216.. So my first one was 1663 and the second 4216 so that more than doubled.. Now it's just a waiting game until March 18th till the ultrasound. Not going to lie. Pregnancy is hard. I'm exhausted all the time and the "pulling" or "cramping" from my uterus stretching hurts bad. I have to pee at least every few hours and I am constantly hungry. I can't even button my pants ha!  My boobs fill like they weigh 20 lbs each and super sore. I'm surprised I'm only 5 weeks and 4 days. Ohhhh and gasssyyyyyyy shew!  I hope all these signs are a good sign that this pregnancy stuck. I'm still not out of the safe zone yet so continue to pray for me!
