May 3, 2009 I started spot bleeding I was worried because that has never happened and plus I heard if you spot bleed chances are your pregnant. The next day I had my regular period lasted 7 days my usual. I normally have irregular periods never the same dates. My partner & I always have unprotected sex for the past 2 years and never have I got pregnant. I figured either he's shooting blanks or I can't have kids. This month is almost over and I still haven't received my period I'm scared I might be pregnant. Last month the last month may 30-june 6, 2009 does that count for this month??

You can take a home pregnancy test with first morning urine after the first week of a missed period.If you purchase a good test such as first response,you should get an accurate result.
If you still do not have a period after the result(if negative) you should see your gynecologist.
Your irregular periods could be because of lack of ovulating.
Best to see your GYN. Just to eliminate any problems.
