Ready to sue my doctor

So I have lost 3 babies before this baby we did some test in last time found out I have low prosetgern  well I had a test done two weeks ago everything can back really high which is great they repeat the test a week later last Thursday... The doctor office called me this morning with what the test was ... She had it back on Friday my levels are lower then what it was on the first test... Soo I'm back on meds which I should have been on a week ago I swear to god I will sue her if I lose this child and I'm looking for anew doctor
