Could I possibly be pregnant ?
I had my "period' 3/4 weeks ago. It was very light and only lasted 3 day.. my periods usually last 5 to 7. I've been having tender breast for weeks now and I've been very tired. I get mild cramping here and there. I took a test yesterday and it came out negative... I'm due for my period on thursay. Please help

Too early to take a test. If you have engage in sexual intercourse, yes you could be pregnant. If you haven't since your last period, then probably not. I would wait a couple of weeks to see if you get your next period and then start testing if you don't. The physical symptoms you are feeling are too early to be due to a pregnancy.

I agree, wait and see if your period comes, a light period, is not uncommon, and should happen sometimes.

You can test, if you miss it, but best testing is two week late.

Also, always first urine of the morning, as soon as you wake up
