Anyone have same symptoms??

I'm hoping I'm pregnant this time! Been kind of trying for a few months now and still no positive test! My periods have been a little off lately. A couple of weeks ago I thought I was pregnant and took a test but it was negative and I also took an ovulation test and it turned positive! So me and hubby did the deed and I've been feeling a little nauseous, slight headaches and cramping.. Yesterday had thick milky discharge (sorry for the TMI.. But it wasn't like a yeast infection) I'm extremely tired all the time.. I feel like I should know how it feels as this would be my second pregnancy but I didn't have symptoms until around 5 or 6 weeks pregnant! Really hoping I'm pregnant, scared to test because I don't want to be disappointed! :-/ anyone else pregnant and having these early symptoms??
