Sheridan,

No I didn't fall pg through IVF - in fact, IVF has never worked for me. Each time I have been pg, it was through natural conception.

But I have long been having HCG measured through blood tests, and I have them a week apart (7 days) when the levels are "good", although for this pg, I had the second blood test done only 5 days, so I could give updated results to my specialist. And yeah, they rose. The numbers don't really matter, so long as the trend is going in the right direction. And you will definately know if it is going in the wrong direction.

For one of my pgs, My BHCG was 50 on day 28 (which is not high for day 28) and then I had a test 2 days later and it was 12. That's a good sign that it is going wrong. AF appeared the next day.

My opinion is that 1 week apart is close enough to monitor HCG levels, but some other ladies what them more frequently for peice of mind, which is fine.
