You should done your HCG hormone test. Levels can first be detected by a blood test
about 11 days after conception and about 12 - 14 days after conception by a urine test. In general the hCG levels will double every 72 hours. The level will reach its peak in the first 8 - 11 weeks of pregnancy
. You should do One abdomen ultrasound
to rule out any other cause for delayed period . if you have 35 days cycle every month then 6th day of period comes in safe period, the chances of pregnancy are very less. Delayed periods may be due to some other reasons like stress, illness, change in schedule, being overweight
or being underweight
. If your pregnancy test comes positive like high HCG level or urine test positive although chances are very less about 1%, then consult a gynecologist. You can use abortion drugs only under the superivision of a gynecologist.
