Advice...

So here's my chart... My husband is being deployed on Tuesday. I definitely have symptoms but haven't tested yet. I'm scared to... But given these dates ect. I'm not sure what to think but I want him to know prior to leaving. My nipples get the random piercing through them, neausea randomly, and the migraines. I have been pregnant twice, the second time this last May, I lost my baby boy at 4 months pregnant. It's been devastating, and this is the first time trying again, I don't think I can really handle a negative test but I'm not sure when I even should test.... Advice? Thoughts?
