Yes, I had this about a week after approx Ovulation, which made me think I could possibly pregnant way before I could test. Such a tease really, hehe. I did end up getting lots of faint positives before seeing the Dr for confirmation. I didn't really get many signs that I was pregnant other than that. A little nausea all day long but no sickness. Just feeling a little off really. My son was 2yrs old when we feel preg, and I stopped breastfeeding him at 16wks, so not sure why I got this symptom either.

It's not a bad sign at all and our bodies can differ alot. I'd say a big congratulations to you sounds like the signs are there.
