TMI photo post- vaginal blood

Has anyone had this? Had af from 22nd - 25th April. Since 27th April I've had brown spotting, not loads but had to wear a panty liner for cleanliness. Today I had some brown EWCM, and a bit pink of light red blood when I wiped about 5 hours but now I've had this. Getting a bit concerned. Ttc and about to undergo treatment but worried this is something serious. I will keep an eye on it and get some professional advice but it's nearly bed time and I could do with some answers!
