Thanks...looks like none of you have had the same thing happen. Earliest test I found was 6 days before missed period and I have a few more days to even reach that. Still took a test and was negative...but still have symptoms. So I will just have to keep on eye on things.
You need to learn how your body works.
Progesterone is the hormone that is produced after you ovulate every cycle. It's the hormone that causes "pregnancy type symptoms" like nausea, sore boobs, etc. If you are nearly two weeks prior to your expected period date (you said you've got "a few days til the 6 day test" so I'm estimating here), there is no way in hell that they are pregnancy symptoms. IF you managed to conceive, the embryo does not implant til around day 6 past ovulation. Symptoms from HCG in your body wouldn't start for at least 36 hours after that, although even that early is rare. You're probably experiencing a surge of progesterone.
It would serve you well to go to fertilityfriend.com and take the tutorials as well as read Taking Charge of Your Fertility. Just because you started on the 3rd of a calendar month a couple times does not mean you're "late" because AF shows on the 10th of a calendar month.
