My last period (feb 26) was six days late. I then bled lightly for three days. I just found out in pregnant and am confused on whether I was pregnant then and I'm two months pregnant or if that counted and I'm only one month pregnant. Help?

The light bleeding is most likely not the period and you were pregnant. This happens esp if you became pregnant near the period date but can happen at other times.
Latter when they do the ultrasound they can make a closer guess at the dates. ** But they are always give or take a couple weeks.

Since you had bleeding that you're not sure was a period, there's really no way to go by your last period because we can't be sure when that was. An ultrasound will narrow down the dates a bit better, but that's really the only thing that will.

Good luck. :)
