Stretch marks appearing and "AF" lasting 2 days

Jackie
So I had a mc in October and since then I can't say that I have had a full period. It last 2 days and is super light and brown in color...I know brown is old so I am super confused. The day I "start" I have light cramping, but when I check my cervix position it is always high closed and soft. I'm not even bleeding enough to cover a line for the 2 days. Plus, I have ztretch marks coming up on my stomach and thighs, but I haven't gained any weight. I feel bloated and my boobs are sore but I summed it up to AF. Yet the stretch marks and my stomach being bloated like it's has my worried. I'm going to make an appointment to go to the Dr. but what do you ladies think?
