Feel stupid asking this really so have namechanged, but I am just curious. Had unprotected sex last month, then had a period 10 days ago. It lasted 5 days which is about normal for me, though was a bit lighter than normal. Now I am worried as a have a few early pregnancy symptoms. Then again, it could all be in my head, so wanted to know if people thought this could be possible before I go out and waste money on a test.
