TMI pics enclosed...please advise

So I had ectopic pregnancy removed alongside with my left tube on 12th feb on Saturday 15th march I had my first AF since op it lasted about 3/4days extremely light for the last 2 of those days. Well I was at my friends house last night and went to the toilet and noticed some brown blood on my underwear see the picture (this is only a week since LMP date tho and then there was nothing but went to toilet just now saw a pinky discharge on liner see other pic and when I wiped it was pinky/red watery. What the hell is wrong with me? Any ideas??​​
