Help!!

Hey I'm new!! We have been ttc for a couple months, the last two, maybe three weeks I have been extremely emotional, been breaking out on my neck and back which usually I don't. This last week has been horrible, I can't stand to be around my s/o and every little thing makes me so mad, oh and then there's the crying, it's like I feel depressed. Has anyone else had this happen? I've taken multiple pregnancy tests but they are negative..Any advice would be greatly appreciated!!
