Fertile Day!!

Today is my fertile day, my partner and I have been trying to concieve; it's been almost 6 months now. I recently started feeling my body-temp raise; I feel a bit nauseated, tired, & my breast are super tender. On my lower left abdominal side I feel a slight pinch and it seems pretty warm. I feel super worn out at the end of the day. The only thing is, I just finished my October cycle & today is my fertile day, I'm scared to take a test because I don't want to see a BFN :( my boyfriend and I have been doing the unprotected sex for the last few months. Anything suggestions? ?
