Testing if I'm 1 week late

I am 3 days late and I keep getting small cramps off and on. Also felt sick and moody yesterday. I was making my husband some honey barbeque chicken in the stove and once I took it out the smell almost made me throw up. My vagina is also staying moist. It's been changing to first being alot of watery, watery/ewcm after ovulation, creamy white cm and now just moist watery. I'm so confused because this never happened before. I used folic acid, zinc and pre-seed this month and I'm hoping it worked. I've normally been on time or a day earlier but I'm 3 days late. My roommates puppy keeps putting his head on my belly and my friends dog also like it just sniffs my belly. My niece is 1 and a half and she would not want to leave my side. Saturday and Monday I saw her and each time she would not go with anyone else, even if I just put her down on the side of me she'll cry She also kept laying down on my belly which she never does when I used to see her. I'm hoping this is a sign I am going to test just waiting till I'm atleast a week late. Did any of this happen to you and you turned out pregnant?
