Late but got my pd chance of still being pregnant

Elissa
I haven't been late in 6months and was a week late and was having nausea and light cramping here and there meaning one day would and one day wouldn't nausea everyday though and tender nipples. Then I got my period and has been light everyday so far. My chest has broke out in pimples and usually don't get like this on my periods just weird overall this month trying to figure out what caused this....I know it's a low chance but I know u can get ur period and still be pregnant....what are the chances I could be pregnant???
