Suggestions for next month

My husband and I just started trying to conceive this month. We tried the 13th and 14th (which was when I was ovulating). Period is due on the 28. I know this may sound strange but I just don't feel like I'm pregnant. I've always felt like I'd be one of those women who would just know, only because I'm very in tune with what's going on with my body. Does anybody have any suggestions for next month? Any advice would be great! Thanks!
