Please help am i pregnant? negative blood test 10 negative urine tests throughout 6 months last sex in december period in december and then in march

Probably not: If the blood and urine tests are negative, then your not pregnant, but you should see your doctor to see why your periods are irregular.

Needs evaluation: Periods are once monthly. When cycles become irregular, it can mean a number of different problems could occur. With this history, i would suggest a visit with a provider for exam and explaination of your situation to figure out a therapy to protect your health and fertility health in the long term.
