At 14 days past ovulation i had an hcg level of 55 and at 16 days past ovulation i was at 104. These numbers seem really low. Does anyone have any thoughts?
They aren't low at all. Its not what the level is at but rather that they double within 48-72 hours which your seem to be doing. At 4 weeks I had a level of only 49. I'm now almost 34 weeks.
As long as they're doubling every 48-72 hours you should be fine. They look good, in early pregnancy they're going to be a little lower, then they'll go higher and higher, level off and go back a little lower before you have the baby.
