Af due 16/3.... Too early for symptom spotting???

Joelene
Hey girls so got a positive opk this month yay....I'm around 6/7 dpo at the moment!!! I never really bother symptom spotting since my pms symptoms are pretty much the same as early pregnancy lol but since yesterday I have been so nauseous...I left work early today I just felt so queasy and absolutely exhausted tired.I'm.literally lying here half asleep... So I guess my question is do you think it's too early for symptoms...or is this likely to be a bug I've picked up x
