Question to all new mums.... 7 months after giving birth, yellowy slight green discharge.... Sorry tmi

I gave birth to my little boy 7 months ago next week, normal delivery bar having to have an episiotomy. I have had about 3 natural periods since stopping bleeding from birth at 5 weeks. However I have noticed over the last 3-4 months a yellowy, sometimes light greenish tinted stretchy discharge, no smell, itch, discomfort, and usually starts after I have ovulate, around day 18 of my cycl, and lasts until my next period. I have had swabs done for infections, and all came back clear, it's just making me feel ununcomfortable, having to wear a pad and inspect my undies everytime I go to the loO! Has anyone else experienced this discharge after giving birth? Or am I unfortunately alone? Xx
