‼️SOS‼️

So as of today I am on CD 120 (crazy, I know) it's because I quit taking my birth control in June and my cycle is still not regular. Well today when I went to the bathroom (tmi) I wiped and there was pink blood on the toliet paper and not very much. I went ahead and put a tampon in because I didn't want a river to come through if I was starting my period since I haven't had one in so long. Well when I changed it there was hardly ANYTHING on there but like maybe 2 brownish spots on it kinda like the last days of a cycle. Now there is nothing. And I have had pretty presisent mild cramps all day. Any ideas?
