Firstly, I need to pee all the time.... My blood tests showed no UTI, and I am peeing normal amounts, but it just seems i always need to go, 100 times worse than in the first trimester...
This is exactly how I have been... I was bad in the first trimester, but 10x worse in second. I guess it is just that the baby is getting bigger now and putting some pressure on the bladder.


And lastly, I haven't put on ANY weight... none whatsoever... I can see my tummy is slightly bigger, but when on the scales I am the same weight I was before... Is this normal?
I actually lost 8kgs in the first trimester. I found that out at 13 weeks when I had to be weighed for my NT scan bloods. I never weigh myself, and I have only been weighed twice during this pregnancy. The first time was at my initial consultation (6 weeks) the second was at 13 weeks as mentioned.
Because the midwives don't place alot of importance on it, I don't feel like I should. Ultrasounds have shown that the baby is growing just how it should be, and my fundal height is normal.

Rest assured that what you're going through is fairly normal stuff. I am sorry that I can't help you in regards to the headaches, but, I have certainly had my share of them too. If you are worried about anything... ask your ob/gp/midwife... but, I think that everything seems to be normal pregnancy symptoms
