Can it still be possible

So my period was jan6-jan9 very short and easy.

I️ was wondering could you still get a little period if you’re pregnant?

So before my period there was brown discharge a couple days later I️ got my period and a couple days after my period I️ was still having brown discharge.

Lately I’ve been having weird pain in my stomach it’s not like a horrible pain but it feels like pressure on my stomach and sometimes there’s sharp shooting pains. And for 3-4 days now I’ve been having white creamy discharge and I’ve been constipated
