Found out my pregnancy is longer

Malaysia
Glow says my pregnancy is 6 weeks 1 day went to the doctor and they told me I'm 6 weeks and 5 days. I went to the doctor cause I had light spotting ectopic pregnancy was ruled out baby was in a correct spot in mommy cramps are on a two scale the doctor said this far chances of miscarriage are low but they gonna check my hcg levels in two days not really worried but fingers crossed.
