Hello,
Thanks for posting your query on health care magic.
Unprotected sex on fertile days could increase the chances of
pregnancy.
UPT is positive after 4 weeks.
It is 98% effective.
I suggest you to wait for 1 more week and repeat the test.
If it is negative, get a tranavaginal USG for definitive diagnosis.
Hope this helps.
regards,
Dr Nilofer
