Test or not to test?🤷‍♀️

Hey ladies,

So my period started a day early and I only had it for 2 days. I usually go for 4 days..I'm wondering if that is a sign of pregnancy should I take a test now? With today being the day after my "normal" period time frame. I had severe headaches for about 24hours before AF actually arrived. I'm trying to determine if it's just stress, overworking or is something actually in my oven lol.
