Missed periods, urine with ammonia smell.  History of having protected sex.  HPT negative.  Possible pregnancy?
Patient: I havent had my period in about 2 months and i am sexually active but we always use protection. We took pregnancy tests and they both came out negative (2 of them) In the mornings. Ive always been very irregular and i get dehydrated easily but im afraid because my urine has been smelling more like ammonia. Im planning on getting a blood test soon to make sure. Do you think i could be pregnant? Doctor: Hi Dear, the missed period may be due to te irregularity in your cycles as you told. You are having 2 mnts amenorrhoea and during this time urine test should come out to be positive. Also you were using precaution. However go for B HCG test to clearly rule out pregnancy because every method has its failure rate and moreover delayed conception is a possibility Good luck
