WEIRD DISCHARGE DURING SEX ???

so these last few days, my vagina has felt swollen and very itchy but just thought it might be a reaction to something. However, when I was having sex, it was quite painful (burning and very itchy) but carried on hoping pain would go, after 5 mins I made by boyfriend stop, looked at the bed and this had come out of me!!! I’m going to go to the clinic but this really scared me and wanted to know if anyone else has had this happen. Its like the consistency of wet tissue and had bits of pink which I’m assuming is blood?? Someone please help as i know this definitely isn’t normal! 😢😢😢 also, there is no smell, just itching, sore and this weird clumpy discharge. Thank you!!
