Help!!

Me and my husband are trying and have been the last month or so. I'm 7dpo by my chart, I'm having a couple symptoms and wanted to know if anyone else has had these, I've had some cramping on and off the last day or two nothing severe but it still hurts, today my nose started bleeding out of no where which is odd cause I never had my nose to bleed like that before. I haven't had any sign of bleeding and I am extremely bloated and AF isn't due until the 14th. I've taken several tests and all came back neg obviously cause I'm to early. At work today (I'm a cashier) my arm ran across my boob and it hurt so bad!!! I had a miscarriage last year and found out cause my boobs were very sensitive water couldn't even touch them in the shower couldn't wear a bra or anything. I just need some ideas of what other think.
