Cramping, bloated, and now light spotting. Pregnant?

Amanda
So I've been experiencing odd lower stomach cramps, mixed with a tingly feeling. Kind of hard to explain, as I've never experienced it before. Bloat for the past 6 days or so. I'm only 103lbs, so any bloat is very obvious. And last night I started spotting, very lightly & light in pink color. All 3 symptoms are not normal for me. My period isn't due for another 6 days, and we had sex all throughout my ovulation days. Now we're about a week out from there. Has anyone experienced these symptoms before, and get a positive pregnancy test? If so, when did you take the test? Thank you!
