Period during pregnancy?

Hey ladies!

So the last few weeks I've been just feeling not myself. Chalked it up to, I must be getting sick or it's the gloomy Wisconsin weather. But now my friends and coworkers keep telling me I have pregnancy symptoms.

I had sex 2 dpo in December and 1 day before my period actually started in January. My period was 4 days late the beginning of January, which is NOT normal for me. Once it came, it lasted the normal 4 days with minimal cramping and semi heavy bleeding. But a week later, I'm still having some very light occasional spotting, feeling super bloated, extremely exhausted, horrible acne, cramping the last 2 days(today worse than yesterday) and I want to eat ANYTHING sweet!

So my question, can you be pregnant and still have a heavy, "normal" period?
