What could it be? Help

Michala
So first month ttc. I'm new here. My last period was October 19-22. Bad cramos, backache, And medium to heavy flow with some clots as usual. I don't use opk or track bbt. Too stressful and pressured. Ovulated over the weekend I believe from cm and cervix position. This morning I wiped and had red blood. Wiped again barely any. Put some toilet paper in my panties. Two hours later a little bit of odd brown color and pinkish color on it. No cramps no pains nothing. What could this be??,
