Hi!
Is it true that hCG levels shoot up only a day or two after conception? (But not _that_ high) This could explains why so many women notice symptoms within about 2-3 days of ovulating - especially the tingling bbs and tiredness. It make sense to me! Last time i was pregnant i was zombie tired just 2 days after ovulation. This tiredness has never occorred cycles that have ended with AF.
HCG is produced by the cells that form the placenta after implantation. Implantation cannot occur until 5 days after ovulation at the earliest. People often mistake their exact O date.
Actually I've found some text that confirm this, but this is not any scientific text..
I'm temping and know when i ovulating. :)
Those symptoms you're feeling are due to rising progesterone levels, not hcg, which doesn't enter your blood ****** until implantation as NBP explained.
Is it possible that your body produce more progesterone when you've conceived? In some way.. It's like i'm having higher progesterone levels really early when we've conceived compared with when we haven't conceived. :)
I'm not even sure what that means but progesterone can cause symptoms as the pp says. Progesterone levels rise after ovulation and either keep rising if pregnancy is established or fall if there is no pregnancy to support. So, 2-3 days past O, it's not HCG.Quote:

Progesterone levels are typically at their highest between days five and nine of a woman’s cycle; after this, hormone levels begin to drop. Day 26 should then be just before a woman’s menstrual period starts. After ovulation, the Progesterone levels begin to rise and the cycle repeats itself. The hormone’s levels rise post-ovulation making a woman more fertile during this period. You can time the level of progesterone by charting your basal body temperature or by using an ovulation prediction kit. Progesterone is at its peak when it is above 10 mg/ml.
Agree with everything NBP says. Progesterone causes symptoms very much the same as early pregnancy symptoms - fatigue, frequent urination, nausea, vivid dreams in my case, gassiness and bloating, etc. Hcg can't be produced till after implantation since before the embryo implants the body doesn't even know conception has occurred, at that point the fertilized egg is just free floating down the tubes and into the uterus.
Crinone or prog supplements produce exactly the same side symptoms as early pregnancy too, so pregnancy-like symptoms at only 3-4DPO are from progesterone, not HCG.
Thank you :)
