Period is four days late. I took a at home pregnancy test. It was negative. Then o had to go to the ER for a concussion. Because they had to give me a CAT scan they gave me another Urine pregnancy test. It too, came out negative. Last night I thought I seen a very VERY small anout of blood on the toilet paper so put in a tampon. I took it out this morning, and there were no signs of blood, but there was some creamy white discharge on it. Something I've never really seen before. I am experiencing what seems to be pregnancy symptoms, but after the two negative tests, I figured it was due to my concussion. Would anyone know if the tests at the hospital are any different? Could i be pregnant? Am I over reacting? With This one... I'm sort of lost. I've never had so much creamy white discharge before. And again, my period IS late... Help?
