Hi,
Thanks for rhe query. I understand your concern.
No chances for the person reffered in query tobe thefather because-
The sex was on 18th of Jan. ... whuch was 6th day of menses&it happensto be in safe zone.(ovulation least possible in periods unless menstrual cycle is 20-'22 days.)
Pregnancy test gives reliable results after 8 days delay in menses . Both the tests were done earlier &cso not reliable. The + ve test on 5-2- 11 must be false +ve due to contaminated urine or container.
Thanks.
