Try not to be disappointed or discourage. It would normally take a healthy couple about 12 months of tryin in order to get pregnant. Symptoms of pregnacy and your period are almost exactly alike for teh first couple of weeks, Nausea doesn’t start usually until you are 6 weeks along. Blood tests are more accurate, and you can be positive as to whether you are or aren’t pregnant. Pregnancy test are not so fast at detecting but most of them work right after you miss your period. Good luck to you and keep tryin, good things happen to those who wait 🙂
