Hello dear
I understand your concern
Urine pregnancy test will give true positive result 7 days after the delay in the period. It has 98% sensitivity.
So if you did not perform test after 7 days of delayed period, then go for repeat test.
Better to go for blood HCG test as it is more accurate test and give positive result even 10 days after the sexual intercourse.
Spotting, nausea could be due to hormonal imbalance, premenstrual symptoms, implantation bleeding/pregnancy.
So you can repeat the test if you had did test 7 days before the expected period date.
But I would suggest to go for blood HCG test as your period is irregular.
Meanwhile avoid stress, take healthy diet, drink plenty of water and do regualr exercise.
Hope this may help you

Best regards
Dr. Sagar
