5 DPO with A lot of Discharge TMI

AnsReal

I been Ttt for 2 1/2 years now with no baby. Went and checked to see if I was infertile and so far nothing’s wrong with me . Any way I’m 5 dpo been feeling under the weather all day and been having cramping off an on on my left side . I just went to the restroom and when I wiped my self globs of a stretchy yellow tinted discharge came out . It doesn’t have a foul Odor or anything . But I’ve never seen this and it’s kinda creeping me out . Can you please let me know if it’s a disease or not . I’m scared
