what is the deal?!

So I was 6 days late last week and I started saturday...i not bleeding now, usually go the full 7 days, so what is wrong with me? I've been exercising every morning (I'm a big girl and my body is sore from using all these muscles I've never used before!lol) so I feel like my body is changing because of me exercising. Should I call the clinic tomorrow or am I just over thinking as usual and get over it? I'm just venting but totally open to advice and suggestions! happy day to yall!!✌❤
