<s>[INST] I am 5 weeks late for my period for the first time EVER, 2 pg tests, neg, hcg blood test neg. I have been feeling all the typical pg symptoms, the past 5 days, i have been spotting pinkish/red, but no accumulation on pad. I ve had a bad lower back ache most of the past 4 weeks. I have had no pms symptoms at all. [/INST] Hallow Dear,Urine test for detection of pregnancy as early as five days after missed period may give false negative results some times. You may repeat the test after 5 more days to have reliable results. The other option is to go for Beta hCG test which is very specific and sensitive. This test gives reliable results even 2-3 days or even earlier after missed period. If all these tests reveal that you are not pregnant, and you do not get your menses, you may take Deviry pills for 5 days. 4-7 days after discontinuing Devery, you should get your menses. I am sure this helps you. Dr. Nishikant Shrotri </s>
