<s>[INST] i think i could be pregnant. the first day of my last period was march 19 2010. i havent had my period this month and i m having all symptoms of it except a positive test and severe pain. i ve taken tests online and they all say i may be. how can i really find out without getting a home test? [/INST] in delayed cycles sometimes urine test is delayed positive. to confirm it go for serum beta Hcg a blood test.if Hcg test negative then you are not pregnant.symptoms can be due to hormonal imbalance. </s>
