Lower back pain ; sea food questions

Adekemi

I am just about 6 weeks and I haven’t had a doctor’s appointment yet.

Woke up yesterday morning with lost of waist pain especially lower back pain. Is this normal? Is there a cause for alarm?

I did take Tylenol and feels much better but still feel it a little. Today I still hv the pain

Secondly, I have been reading about pregnancy and fish/sea food. So is it that I can’t eat any at all or am I to limit it?
