Weird and long periods post lap

[Porshia]

Hi,

I had my laparoscopy surgery(excision) in June to remove multiple endometrioma on my ovaries. The cysts were around 3, 4 and 5 cm. Post-surgery I was given a shot of decapeptyl. I got my first period in July which was pain-free. Then for 2 months didn't get any period. After that, got my period in October and then in November. It's been 10 days now and I am still bleeding( The flow was high for 4-5 days and after that, it is less but still there). Sometimes it's red, sometimes it's brown in color. Is it normal? Or is my endo back? Please help
