I've had sex unprotected multiple times. I thought I was pregnant for a while then I took a test the test said I wasn't pregnant, but I still felt as if I was because of nausea, tiredness, always hungry, and feeling swollen everywhere. I started my period on the 24th but it was dark brown and very light, not heavy at all. The next morning on the 25th I didn't bleed at all that night. And through out that day I didn't bleed more than a teaspoon of blood, so today being the 26th I have not bleed anything. I know my partner and me had no STD's because we both got tested. All the pergnancy test I've taken said NOT PREGNANT. What's going on? Could I be pregnant?

Pregnancy is possible... sometimes it can take even a few weeks before a pregnancy test will pick it up... or it could be an off period.

Try another test in about a week, following the directions exactly. If still negative, wait and see what happens when your next period would be due or you could see your doctor and ask about having a blood test done.

On an off period, can you bleed before you have your actual period?

Were you due to start your period on the 24th or was it a bit earlier than what you expected? If you aren't yet due for your period, see what happens when you would normally expect it. If you test again, and get another negative result, but you still have the nausea and such, ask your doctor about having a blood test done.

On the 26th
