HELP! 11 DPO should I test?

Kimberly • 22 years old. Wife. Teacher. Went off birth control pills in January 2016 and TTC since. Baby dust for us all! ✨
I'm very nervous to test with my FRER. I tested with wondfos yesterday. I have a cold so that could account for yesterday and today's higher BBT temp. I need you girls to help me decide! It's hard to see a negative. Only symptoms have been fatigue since about 6 DPO, low back pain, acne, gassy, emotional/moody, and this cold came out of no where. I was sick 3 weeks ago and it's unlike me to get sick 2 times in one month. I also had diarrhea bad all day at 9DPO. What do you girls think?
