The last week or so I have had blocked sinuses, headaches, tiredness, nausea, heartburn, and increased appetite. My period is due today but I do have an irregular period. Usually a few days before my period I get intense heartburn and spotting, but so far only the intense heartburn. My boyfriend and I have been ttc for a year now and with so many bfn's I am scared to test. How long should I wait to test?
