Postpartum depression and anxiety.

I had c-section on 15-11-23, after two weeks I started feeling anxious and depressed, I went to meet my psychiatrist she prescribed me sertraline 25mg for a week and start 50mg for 3 weeks, also clonazepam 0.25 (sos) , after one week of 25mg I started feeling nauseous, loose motion, stomach grumbling, and more anxious, so I went to visit my psychiatrist again but she is out of station, I can't stopped the meds cold turkey so I continued with sertraline 25mg along with clonazepam (half of 0.25) , now my nausea and loose motion is gone, but stomach still grumbling and hardly sleeps for 4 hours straight, and feel anxious (controllable) when I wake up, today is my 14th day with setraline 25mg I went to visit my doc today but she is still on leave, I don't know what to do, I want to up my meds but I'm scared of side effects like nausea and loose motion again. Please help me what to do, shall I continue with 25mg or start 50mg by tomorrow? Please help me please Thankyou
