With my first miscarriage, I didn't even know I was pregnant when I lost her. I was just over 2 months, so I couldn't tell you. I had more pressing things on my mind at that point, trying to recover from the trauma of rape.
With my second miscarriage, we suspected I was pregnant. My boobs hurt and were swollen, I was always sick, it was harsh. I was 2 months and some late. We had just decided to take a pregnancy test, and two days later (before I got a chance) I woke up bleeding very profusely and felt like I was being stabbed in the stomach.
With this pregnancy, I was only mildly sick (only two throw ups. YAY!), but was always nauseous. Smells bothered me, and certain tastes did. Only lasted til 3 month mark or so.
So I guess my answer to your question is yes, same symptoms, but FOR ME at least, they were much milder with this pregnancy, and I am now 28 weeks.
