Pls help us with the remedy that what should I do now... please help... pls help...

Pregnancy is very much a possibility. However, the stress so pregnancy can delay her period. Calm down an relax. Test again using first morning urine when her period is two weeks late.

If she is not pregnant take this as a learning experience. If the two of you are not prepared to be parents, refrain from sex.
