Sore throat

So we have been trying to conceive for about a week now. According to this app. I'm in the 15% chance of getting preg. I got a pretty sore throat yesterday and bad stuffy nose. Just feeling like I'm getting sick. I googled it thinking I would get back nothing and there were actually woman who experienced flu like symptoms really early. Am I just getting hopes up or could I be conceiving? The sore throat possibly me getting pregnant? Anyone else have one?
