Hi dear user, thanks for your query.
You didn't mention your menstrual history clearly. Bleeding, which you had after first intercourse, might have been because of rupture of hymen
or your natural period. Pregnancy
cannot be decided only on the basis of increased hunger. If you are over due by more than one week, then i will advise you to go for pregnancy test( urine pregnancy test/ serum beta HCG
levels). There is no use of birth control pills in this cycle now.
Hope this helps.
