The only symptom I have is heavier breasts, no m/s and really no nausea. Though with my last pregnancy that all kicked in around 7 weeks for me. I used to worry a ton about fewer symptoms but ever since I began working in a busy hospital ER/Trauma center I realized it's totally normal. Every woman is different. I work with a ton of nurses whom have all been pregnant at some time or another so it's always interesting to see how pregnancy is different with all of them.
We have one that is about to deliver who was never sick or nauseous not 1 day in her pregnancy. We have 4 others that are pregnant and not one of them is a puker. Yet my sister's, SIL throws up multiple times a day. And then we have one of our doctors that's pregnant and she has hyper emesis, which I would never wish on my worst enemy.
Plus a lot of woman who do have miscarriages will have strong pregnancy symptoms right up until the day they miscarry. So as much as it's so easy to analyze every single symptom, it's just something that's really unique to each individual woman.
