Thanks for the query.
If you had unprotected intercourse
around the time of ovulation, then there is possibility of pregnancy
And the pains you are having could be due to implantation
In the absence of pregnancy the pains can be due to hormonal changes or there could be some possibility of infection.
And now it is early to comment about the pregnancy.
So you wait till your expected date of periods and if you miss the periods go for pregnancy test once. Start taking folic acid
tablets from now-onwards.
