I’m so confused

So my periods are 7 days long. They used to be heavy the first 3 days then light (I would say not super light, but not as heavy as the first 3 days) for 2 more days and then some spotting the last 2 days. Ever since June, my period is heavy the first 1 or 2 days then it’s just super light the rest of the cycle. I’m usually halfway out of pads by the 3rd or 4th day but I’m not anymore. Is this normal? I’m 21. I am married so I’m sexually active. But I feel like something is wrong. I keep googling this and I’m just not sure if my period is “abnormal” now
