Ughhhhhh not feeling right

Today has been very odd for although me and my husband have been trying to get pregnant I got my period 8 days early and only mild bleeding for 3 days so it's been a few days since my period stopped so for the past week I've had a increase in appetite and today I was very hot my face was sweating my body just felt hot and then I started feeling light headed and a really bad headache I'm feeling so miserable I'm not sure if I should test or not beings tho I just had my period what should I do?
