Hi, I had my last period on July 27th and after I got sealed to my husband on August 7th we started trying for a baby. I haven't had a period since but have been having many pregnancy symptoms. I took about 6 HPT all negative the doctor did 4 urine tests and a blood test on the 4th all negative and no thyroid problems, diabetes or any other problems. Can I still be pregnant or is there another reason I'm missing?
