I was supposed to start my period on the 31st of March and end on the 7th of April but all I have been doing for the past 4 weeks and 1 day is spotting really light pinkish Brown but no clots. I had a blood test done 9 days after missed period but it showed up negative could I still be pregnant. My higher fertile day for my last period way the 16th of March which me and my old man had unprotected sex and my last period was February 27-March 5. Please help I have all the symptoms but I don't know what to do
