Feeling anxious

Since i've given birth i've been very anxious for no apparent reason, and just feeling not quite myself. I'm not unhappy or angry or anything i'm just feeling a little unlike myself..i'm still able to do things normally, have no issues taking care of my daughter or other two children so I don't know what's going on..wondering if I should possibly talk to my doctor about medicine for anxiety? I don't believe it's post-partum because I don't have a lot of the signs just the anxiety..so I don't want to be put on all these medications for no reason, just wondering if anyone else felt like this about 12 days after giving birth? I don't remember it with my other two

I'm always kind of anxious, or wound-up. I worry about everything.. especially since having kids. I'd definitely talk to a doctor, but my doctor doesn't want to prescribe meds for anxiety.. he thinks it can all be treated with therapy
