Abnormal discharge mid cycle?

according to glow I ovulated two days ago. yesterday i had a small drop of red mucousy discharge.. It was no bigger than the tip of a pencil eraser and I've never had any mid cycle spotting before. It was like clear discharge but with blood in it. That was the only weird discharge I noticed yesterday. Today I had really stringy clearish discharge mixed with brown it almost looked yellow in the light but against toilet paper/white background it was brownish. Should I be concerned about this?? everything I've looked up says either hormonal imbalance, possibly cancer, or pregnancy. Definitely should not be the latter considering my husband has a vasectomy lol

I'm 21 and I do not take any kind of BC im not aware of any hormonal imbalances and my periods are regular im just worried now please help me... :-)
