Hello ladies. I had my first BFP on 4/28 and the tests have been getting darker since. I’ve had light pink / light brown spotting on and off since yesterday. I had bloodwork drawn yesterday morning and my HCG levels were 492. I go again tomorrow morning to make sure they are rising. Should I be concerned? I have PCOS and my LMP was 3/20. Doctor thinks I may have ovulated later due to my HCG not being as high as expected. Should I be worried?

::Update::

Also, my progesterone levels were 10.1.
