Welcome to HealthcareMagic forum.
the symptoms you have given above are not very significant or specific for a pregnancy
,though they may be related and seen in pregnancy , the best sign is missing the coming period .
Since it has just been 5 days , I would ask you to wait for for another 5 days and do the urine pregnancy test .The kits are very easily available in a pharmacy , confirm your pregnancy and act accordingly.
Wish you good health
