Need some advice...

Ok so this might be TMI, but I am almost nine weeks postpartum after having my second child. I've already had my first postpartum period which ended about 14 days ago. Well, the past two days, I have had brownish bloody discharge and some bright pink streaks in clear discharge along with back pain, and sharp stabbing pains in my left ovary. There is also a constant crampy feeling in my uterus and my cervix feels raw as well as my birth canal area. These symptoms are in addition to me not being able to eat much and feeling very sick afterwards. However, I have experienced that since giving birth. It's just not went away. I can literally eat a meal and go to the bathroom within an hour after eating, so I try not to eat to avoid it. The worst part is I've actually gained weight...I just don't know what is going on with my body and if this is all normal for a postpartum mom in her late 20s or not. I definitely don't remember this with my oldest child..I do have an appointment with my doctor in the morning, just wanting to see if others have experienced this and what it was.
