I'm officially 9 days late, five HPT's and one blood test have all had a negative result. The only "symptoms" I have, be they associated or not period or pregnancy related, are daily headaches, increased body temp (typically I'm always chilly), mild cramping on and off, developed sore breasts yesterday. I have no other symptoms towards PMS or pregnancy, and my body is not behaving as it has in recent years before a period. I've not recently started or stopped any medication, I have no medical conditions, no symptoms that would indicate a vaginal/urinary infection, I haven't been under any higher than usual stress levels, and I have never been late for a period except when I've been pregnant. I'm 30 years old, with two children, so this is really bugging me! Every pregnancy I've had, be it live birth or miscarriage, I have always had a positive HPT before or soon after my missed period. I've always been very intune with my body, so to have my body be so "out of whack" is really throwing me for a loop! The dr said I should re-test again in a week and if nothing shows up to fill a prescription for something that will force my body to have a period, to "reset" my cycle. Is there anything else that could be causing me to miss a period or have it be so delayed? How likely is it, given the negative urine and blood test (blood test was done at six days late), that I could be pregnant? I do have unprotected sex with a committed partner 2-3 times per month, but have always been intune enough with my body to avoid unwanted pregnancy. I've managed to not get pregnant for seven years just using natural family planning. The last time we had unprotected sex was 14 days ago. I'm wondering if perhaps I ovulated late and just didn't notice and that may be the cause for either a late period or negative on the pregnancy test because it would still be too soon to pick up the HCG.
