11dpo Symptoms

Megan
I am SO nervous to test this month - or to even say out loud that I think I am pregnant! We have been trying for about a year and a half. I've had four IUIs and so far, no luck.
​My SIL just announced she is pregnant, which is both exciting and devastating. I'm hoping that I'm not tricking myself into feeling symptoms at this point, but here they are:
​- extreme nausea 9-11dpo
​- headaches
​- dizziness
​- breast pain (sharp pains pretty often, but they aren't tender to the touch)
​- breasts feel heavy
​- cramping (could be AF)
​- runny nose, sneezing, watery eyes
​- crazy mood swings
​- sleepy 
​I feel like it's too early to have the symptoms I've been having, but I have never felt a lot of this before. Do you think it's too early to test tomorrow (12dpo, AF due 3/30)?
​Thanks!
​P.S. In all the time we've been trying, this is my first time posting/participating in a community and I have to say, it really helps!
