Yes, each pregnancy can be a bit different. Try not to worry. For most women that DO get morning sickness, the average time it starts is week 6 to 7 because it takes that amount of time for the hormones to build up enough to cause it. So, don't rule it out yet . . . good luck
Yes. I have a 15 month old and I am 5 weeks. With her i was sick and felt every symptom early but this time around the only symptom i have is a missed period. I feel great! I wouldnt think i was pregnant of ot wasnt for the blood test.
