Hello and welcome to HCM,
I am Dr Nilajkumar a consultant gynecologist and I will be helping you in your queries.
Urine test will come positive 3 weeks after conception. So if the day of contact was 16 days ago, you must wait for another 7 days before the urine test to come positive [ add 36 hours for ovulation conception period].
If the ejaculation was outside then chances of pregnancy
are very low.
Also please use a contraceptive
like condom in future to avoid stress
and also prevent sexually transmitted diseases.
Stress also delays periods. So relax and check after 7 days. Most likely you will have a period by then.
Hope this was helpful.
Feel free to ask any further queries and I will be happy to help.
Thanks for using HCM.
Have a good day.
Dr Nilajkumar Bagde
