On day 8 of period and freaking out..

A little back story. I'm 36 I loss my daughter at 16 weeks pregnant. It seems like ever since then my cycle has been longer than normal. I use to have AF for 6 days and now it's 7, now 8 and it's looking like possibly going into 9 days. I have a doctor's appointment Wednesday morning. I would like to have another child so are my hormones still out of whack from the loss? I'm also on Wellbutrin for ppa and depression from my first pregnancy. I just don't know what to think.
