I haven't had much of a appetite.. i love eating but now a day after intercourse i wipe and had lite pinkish blood dried up it looks brown. pregnant?

That would: Not be a sign of pregnancy 1 day after intercourse; doesn't mean your not pregnant but sperm takes time, 36-48 hours or so to even reach the egg which doesn't start implanting until around 5 days after ovulation. Post coital bleeding, if it persists can be an issue, not to scare u, i'm sure your fine, but it can be associated with an infection of the cervix so get exam if persistent or pain.Gdluc.
