Thanks for the query.
For getting pregnancy
you have to plan unprotected intercourse
around the time of ovulation, which will increase the possibility.
You can track ovulation with ovulation kit in the middle of the cycle between 14th to 18th day according to your cycle.
Just by symptoms we cannot confirm or rule out pregnancy., so you wait till your expected date of periods and go for pregnancy test once.
Start taking folic acid
tablets from now-onwards.
