Hcg levels rising but no doubling

Hey guys. Have my transvaginal scan tomorrow morning and I'm a little worried, had slight spotting on Tuesday only lasted like 3 hours, only when I wiped nothing on panty liner. So my hcg levels on Monday were 715, and Wednesday they were 1058. I'm a little worried, My nurse said sometimes it can take 3 days for them to double, she wasn't too concerned as the had increased. Anyone go through this and have healthy babies?
