Feels to good to be true

I've been testing all week.. and each time my lines get darker and a digital confirmed yes. My husband and I are TTC and this was our first cycle, I just CANNOT believe it happened! When I first started testing I was getting faint positives and was scared of getting a false positive. I really didn't think I would get pregnant this cycle cause idk, I read a lot of stories on here and I was like well it's my first time trying ever lol. Well, I keep getting positives and why doesn't it feel real? Has anyone gone through this? Like it hasn't hit me that I'm pregnant, feels like it's still the normal day in and out. Like why?? I just can't believe it, why hasn't it hit me yet? Has anyone felt like this?! My doctor won't see me for another 3 weeks. Plus my period isn't "late" til after the 16th, guess that's another reason why! I'm also real scared of a chemical pregnancy. Does anyone know when your in the clear of that? I know your not in the clear for miscarriage until around 12 weeks! I'm going crazy! So much on my mind 😳 pregnancy hormones hitting me already! And my husband doesn't know yet, I'm planning a way to tell him and I wanted to tell him this morning when we woke up, but we got into a fight last night and now it just ruined our moods. This is also making me go crazy bc NO ONE knows I'm pregnant but me:( and you guys of course... but sorry just need to vent because I'm keeping this all in and can't talk to anyone yet til I tell my husband, but I was waiting til I defiantly knew I was! I'm feeling crazy emotions lately and feel the change in my body. Are the hormones suppose to make you feel like you have a million thoughts and SO MOODY and up and down?!. Has anyone else related to this??
