So I'm 7 days late today, was due on AF on the 30th and still no sign of it at all. No spotting or anything. Always had regular periods. Feeling like my breasts are heavy, urinating a lot but no other symptoms. Took tests for last 6 days and all negative but doctor won't do a blood test yet. Am I testing to early? First child so I don't know what to look out for. Any advice please
