Okay lady’s this might be tmi, but I need some input on something.

Okay this time my period was 5 days short and my period normally 10 days long. After this period I’ve been sick in the morning throwing up after I eat and when I smell things that are bad it makes me throw up. And I was just wondering if you can get pregnant while you had a short period? I really don’t think it was a period tbh, it wasn’t heavy at all this time. So should I wait to take a pregnancy test to see if I miss this next period or go ahead and take one?
