What do you think?

Yesterday I had pink spotting when I wiped. I thought my cycle was coming on so I put on a pad. It didn’t even fill it. Just some pink and brown discharge. I have very molding cramping which is not like my usual PMS cramping and my boobs are sore either and they usually are the week of my cycle until it comes on. Today while I was in the shower this came out of me. Still having pink and brown bleeding, not enough to fill a pad. What do y’all think? Is it just breakthrough bleeding and old tissue or something else? I feel I’m out for the month but I’m trying to stay positive.
