I need advice..

My so & I have been trying to conceive for 8 months.. Not really any luck. I got my hopes up last month when AF was 4 days late. :( this week, today actually I ovulate. But I've been feeling different. I felt sick all day like I've wanted to puke at everything I've ate today.. I know it's way too early to even think about testing, but any advice as to trying not to feel this sick.. I don't even know why i feel this way, I haven't felt sick the weeks i ovulated in the previous months... I just don't want to get my hopes up again for another BFN.. :(
