Early signs!?

Shelby
My husband and I bd'd on my most fertile day! I swear since 3dpo I have had mild cramping off and on during the day kind of like right before your period is starting. However I never cramp this early. Starting 5dpo I started feeling crummy at night. My mouth gets really watery like before you throw up. I'm only mildly nauseous though. I hope I'm not making these symptoms up in my head! I know I am not making the cramping up. I think this month might be it for us! I swear that as soon as that little swimmer meets the egg it starts giving off hormones. I think that it is possible to feel these early signs!! Does anyone else have any thoughts? I'm going to test at 10dpo. Today I am 8
