progesterone level dropped

Me
Need feedback. I am 7 weeks pregnant with our rainbow baby. All my levels last week were perfect! I get my lab results emailed
To me which could be a blessing in disguise bc the docs office hasn't even received them yet. I got a slew of bloodwork done on Friday and my progesterone level dropped from 14 (taken June 17) to 
11 (taken June 23). I called the nurse in a panic and she immediately called in progesterone pills. Has anyone taken and had a successful pregnancy? So scared
