Am I pregnant

So I would like to think that I’m not the only one who has some stopping after a period . Morally it’s just for 1 or 2 days. But I’m on day 4 and it’s not the same amount each day . Like today I thought I was all done and go to the bathroom and it look like I may be starting again. My husband and I had sex a few day ago without using anything. I think it may in plantation bleeding . This would be my 2 baby our daughter is most 2 and I never had any bleeding with her. Also I am having some pain today too.
