I had a bloated stomach and sore nipples. Morning sickness didnt start till much later.
I don't think there are any actual signs since every person and every pregnancy is different. I didn't show typical pregnancy signs until two weeks after my missed period; nausea, vomiting, fatigue, sore breasts, ect...the only problem with these signs is that they usually mimic PMS signs so you can't read too much into them. The only true sign of pregnancy is to wait until period is due or late and take a test or go to doctor for blood work.
there is bloating, vomitting/nausea, sore breasts, cramps like AF is going to arrive, constant running to the loo, smells become stronger, implantation bleeding etc but believe it or not i have these every month and i have yet to conceive, the best way to know if you are pregnant as far as i'm concerned is wait a week after missed AF and then test. Best of luck to you!!
