My period was a week late and I thought I was pregnant so took a test at lunchtime but it was negative but I was told I should do it first thing in the morning so I'm going to do one tomorrow morning. However I got cramping for about 4 days and this morning wheni went to the toilet and wiped(sorry too much info)it was very light pinky colour so thought my period was started I put a towl on but had very little bleeding since, could I still be pregnant. I had sex 2days ago unprotected as we are trying to conceive is it too early to think I could be pregnant?
