Help with possible rabies

Ohk i got bit by around 2 dogs around 8 days back. Now i immediately rushed to a nearby hospital where my wounds were thoroughly cleaned, and i got my anti rabies vaccine shot. Today is the 8th day and i've taken 3 vaccine shots plus the initial tetanus shot. Now the bite was just a nibble and nothing was ripped off from my skin but there was blood which was cleansed thoroughly. Now day before yesterday i went with a friend to a restaurant to eat some chinese food. Yesterday when i woke up, i started having a bad stomach and a mild headache which activates when i bend down or move my head furiously. My friend also had a mild case of dysentery(6 times in the day and liquidy, if you know what i mean), but hes fine now. But today when i woke up, the headache is still there. Also, i felt slightly feverish yesterday, but its fine now. Is it too late for me? Or is it just a stomach infection. I can't shake the feeling that something bad is about to happen. But i don't feel malaise today as i was feeling yesterday night.

P.S. The dogs were beach dogs which my doctor says are usually vaccinated. Also there is no tingling sensation at the site of the bite, but it pains a bit if i press on the site of the bite, which should be normal. Once again i've taken 3 rabipur shots at the prescribed times.
