Okay so my husband and I have been trying to conceive for the last 8 months. My period has been regular the whole time. This month is different however. We calculated the ovulation cycle trying to plan for it and now I am 7 days late I took a test at 4 days late and it was negative. I can't say I really have all the symptoms but my breasts are a little tender and I have some nausea that comes out of nowhere.
