Period 2 weeks late and then bleeding for 2day

Pinky
Hi there, i'm 30 years n trying for baby for the last 4 months. My period was 2 weeks late this month and the HPT showed negative. Finally i got my periods on 26/09 and this time my periods lasted only 2 days. Today is my 3 rd and there were only 2 spots since morning. My period will usually last 5-7 days. Is this normal? Is there any chance i could be pregnany? If so, when is the earliest i can retest?
