Thanks for the query.
Though some of your symptoms suggesting pregnancy
, just by symptoms we cannot come to one conclusion.
If you had unprotected intercourse
around the time of ovulation then there is possibility of pregnancy.
You once go for urine pregnancy test to rule out the possibility of pregnancy.
If the test comes positive it is good, if not you go for ultrasound
to find out the possible cause for your delayed periods and take treatment accordingly.
