Does nausea begin when the HGC levels rise? A little on my background and reason for question: Mid Dec I began with pregnancy symptoms that have continued on and off. Done many tests, all negative. I was 10 days late on my period when I had a pretty light period lasting only 3 days. This is out of the ordinary for me. I'm a 5-6 day girl with heavy periods. I was convinced it was a unusual period and decided the negative tests were correct. The last 3 days I have been having sickness shortly after waking up, lasting for up to 2 hours. Sometimes having a nibble on something light or going g back to bed can settle the nausea down. I've heard that nausea is at its worst when HGC levels peak (at around 6 weeks). Is this right? I need to do a test really but reluctant to start this cycle of testing and obsessing. It could be that I'm starting with something too, but seems odd that had a conceived in mid Dec, I am at the *peak* of HGC as Google implies.
