Kinda new need some help thanks in advance..

Hey everybody I'm new to this app. I'm ttc but then again I'm not. I want a baby but don't because I'm scared It will be my first. I'm 23 and my SO is 24 and we have been together for 8 yrs. I'm having some symptoms but not sure what it could be. My symptoms are nausea with no vomiting, dizzy, headaches, no appetite and then I get times where all I do is eat: / I'll get like these pains in stomachs area like I've done a million sit ups Lol and I also had some blood on toilet paper a few days ago but just for that day and that was it AF is not due till the 22. Please help and baby dust to you all
