I just had baby 2 weeks ago by csection and I want to know what is the signs of a blood clot??

Firstly, let me congratulate you!!

Secondly, blood clots can develop anywhere in your body after delivery.

Can you fill me in with the signs and symptoms of why you think you are having a blood clot?

Well I have a lot well first my leg started to hurt but went away and then it got really hard for me to pee for to days and then I had really bad back pain and I mean really bad

Where exactly was your leg hurting?

Back pain and hard to pee sounds more like a UTI, either bladder or kidney.

Either way, you should get this checked out.

At first it was at the back of my calf and now its at the back of my thigh

It may or not be a blood clot. But I will advise you STRONGLY to seek the advice of your doctor.
