I was nautious for like 3 mornings in a row last week then my boobs stated to hurt a few days later and itch a little. I took a hpt but it was still 9 days before I missed my period. Should I retest?

You need to wait until you miss a period and then wait for about 2 weeks after that before you can hope for any accuracy from a home test.

PMS and pregnancy symptoms are almost exact. It's very possible that the symptoms you are experiencing are PMS.

Like Odinn said, it's way too early to test. Wait until your period is due. If you miss it, wait 2 weeks and then test with first morning urine. If that test is negative, wait until your next period is due. If you miss it, test again or see a doctor for a blood test.
