Period question

Katelyn

Hey guys I have a question. My periods usually last for 5 days and they don’t let up until the 4th day. Today on my 3rd day I noticed that my period was about to stop and the blood became really light and pink. It got a little heavy yesterday but nothing what I’m used to. Could you still be pregnant and have this happen? I know you can’t be pregnant if you have a period but would you consider this a period or just a short cycle? I’ve been peeing a lot also and I’ve been nauseous. But all of this could just be from my period.
