You are 28 dpo and am 8 days late you had spotting 3dpo now your period is all hpt saying negative what can it be?

If you are 28 days past ovulation (DPO) and 8 days late for your period, it is unlikely that you are pregnant. A negative home pregnancy test (HPT) at this point is usually accurate. Spotting 3 days past ovulation (DPO) could have been implantation bleeding, but it is also possible that it was simply spotting unrelated to pregnancy.

There are a few other possible explanations for your late period and negative HPT results:

* Anovulatory cycle: Sometimes, a woman does not ovulate during a menstrual cycle. This can cause a late period, but it will not result in pregnancy.

* Underlying medical condition: A late period can also be a sign of an underlying medical condition, such as thyroid problems, diabetes, or polycystic ovary syndrome (PCOS). If you are concerned about your late period, it is important to see your doctor to rule out any underlying medical conditions.

* Ectopic pregnancy: In rare cases, a woman can have an ectopic pregnancy, which is a pregnancy that occurs outside of the uterus. Ectopic pregnancies can be dangerous and can cause life-threatening complications. If you have any symptoms of an ectopic pregnancy, such as severe abdominal pain, nausea, vomiting, or vaginal bleeding, it is important to see your doctor immediately.

Overall, it is unlikely that you are pregnant if you are 28 DPO and 8 days late for your period, with all home pregnancy test results that say negative. However, it is important to see your doctor to rule out any underlying medical conditions that could be causing your late period.
