Hi. My husband and i have unprotected sex all the time but i am on birth control. However, more often than not, i take it quite a few hours late. Over the past 2 weeks, i have been nauseas and gagging to certain smells of food, and my temperature has been going up and down between 98.5 and 99.5. I have also noticed that i am SUPER hungry every 3 hours, which was not the case before. I am supposed to take my last active pill this coming friday, however i just now started spotting light brown mixed in with my normal discharge. is this a sign of possible pregnancy? should i go get a home test?
