Question ladies ?!!!?

Update: it was only 4 days.. real light. & today we drove to the mountains and I got really sick. I’m not sure if it was the car ride or what but I even had to vomit 🤢

I had my period last week. But I’m so nauseous and so tired. Can I be pregnant??? Is that even possible?? My husband and I haven’t had sex since before my period. Has this happened to anyone else ???
