Thats a very broad question just because numerous
pregnancy symptoms are also symptoms of other things. For me I had no symptoms (other than my missed period) until week nine. Then I had nausea, vomiting (typical morning sickness), tender beasts, light lower abdominal cramping, and exhaustion. Mind you though I usually had all of that (minus the vomiting) a day or two before my period would show up. Even the nausea lol.
