HCG LEVELS...CAUSE FOR CONCERN?!

Heather

hello ladies I recently got my BFP and have been to the doctor twice now to get my hormone levels checked. I went this past friday (two days ago) and then today - Sunday. with less than 48 hours in between. My HCG level on the first test was 90. My test today showed only 125. I thought HCG levels were supposed to double every 48 hours?! my is obviously slowly rising. My other levels went up a good amounts from the last tests i.e. my E2 and P4 are both good but now im concerned my levels arent rising fast enough and not sure how to feel about that. they want to retest me in 3 days later on Wednesday this coming week. Any ladies have slow rising HCG and it was okay or should I be concerned?! not sure what you can even do to make them rise but any advice comments experiences are greatly appreciated. thank you in advance!
