Thanks for posting on HCM
From your description, you are presenting with typical signs of pregnancy
with missed period ( 39 days amenorrhea
and the other symptoms plus the fact that you had unprotected sex just around 14 days post your 1st day of last menstrual period. This greatly increases the chances of you getting pregnant. Doing a urine pregnancy test now or dosage of beta HCG
in blood will be a good way to start. If pregnancy test is negative then paying a visit to your gynobs will be well indicated to rule out possible infection or underlying diseases.
Hope this helps
