buy it or not?

So I gave been going to the doctor because ive been having trouble TTC. My husband works out of town so it has been hard with the days of ovulation and stuff. Luckly last month he was here the day of ovulation, my doctor told me that if by the 8 of this month I had not had my period yet, it was more likely that I was pregnant. The thing is that I am so nervous in buying a test because honestly I do not have amy symptoms and I do not want anymore false hope. What should I do?
