Yep, feeling more sick again today...
It is perfectly normal for your symptoms to fluctuate during pregnancy. I usually have diarrhea for a week then constipation for the next.
Thanks LynnB9, after reading your response it occurred to me that I have been drinking less water and have been out of my normal routine being off work for the holidays ...
If you are worried you can always call your doctor and check with them. I am only 5 weeks and 4 days, but my symptoms vary by day and hour. I've had a good day so far with only on bout of nausea. I know from my husband talking with a pregnant co-worker that her symptoms disappeared around 9 or 10 weeks. Your body could be getting use to the higher levels of hormones.
To help with the hard stool, make sure you are drinking enough water.
I saw stats somewhere, that something like 25% of all women have no early pregnancy symptoms. I was hoping I would be one of those lucky women... sadly... its not the case.
