Was having pregnancy symptoms and I woke up feeling fine today. Is that normal at 6-7 wks?

Pregnancy symptoms can come and go like that, especially in the early weeks, so it's pretty normal to wake up feeling better one day. That said, since you were having quite a few symptoms together (nausea, breathlessness, feeling woozy), it might be good to bring it up with your PD or KKH just to be safe and make sure everything's progressing well, rather than second-guessing whether the sudden change is fine or not. They can give you proper peace of mind.

I feel you. But is normal for the symptoms to come and go. Some days i feel perfectly well, some days feel like crap. But so far been sleeping well. Same here wk 7. But if breathlessness getting worse better go to the kkh emergency clinic
