I always get this every time I go to the restroom ! It's not when I wipe but when I am done I see it on the toilet and it looks like a blob . Yesterday I had a pain on my left side abdomen and discharge as if I had ewmc but I already ovulated ? I've been bloated& I had constipation for 2 days until today . I also feel like I'm getting a cold because my nose gets stuffy when I wake up and a sore throat. I am 8dpo and AF is expected on the 8th .  When should I test ? 

Edit : I have been more gassy than usual as well !
