Ulcer (or at least that's what I think it is)

I've been getting what I think is a stomach ulcer in the last 2 weeks. I don't think I've skip meals, I've been eating regularly and frequently so it can't be the cause of the problems. Besides being pregnant I'm hungry all the time!

I'm trying to remember what I did on the day(s) when I got the stomach ache, and I've come to conclusions:

1. (Decaffeinated) coffee
I'll never drink coffee again, at least until the baby is born and see how my stomach will take it. I love coffee and although in the beginning of my pregnancy I hated even the smell of it now I'm starting to like it again. If now I'm desperate I'm just going to have a sip or two, no more.

2. Tea
Limit to only one cup a day, maybe two if when I really want it but not consecutively, i.e. one in the morning, and another one at late afternoon.

3. Fruit
Not in the evening or after dinner. I noticed my stomach ache comes at late evenings. So fruit is to be eaten during the day and not after 5pm.

4. Getting cranky & stupid over my messy daughter
-Eliminate the source;
At the moment I'm sorting her books and toys, with her approval of course otherwise I'd be in trouble when she wakes up the next day to find her empty shelves! I'll only keep a few things she likes to play with, and get rid of the rest. The reason I kept the rest of the toys/books in her room is because they usually stay where they are at the shelves or in the basket. But lately when she's bored she just takes everything out and after every thing's on the floor and messy she claims she's too tired to pack away! And of course mummy (that's me!) getting all worked-up & cranky - hence, getting herself a new ulcer!
-Solutions;
Needs to be more relaxed which I find really hard lately. I think during pregnancy my level or tolerance has dropped dangerously low.
Needs to have warm baths more often, with various calming effect scented aroma therapy bubble bath. And whilst in the tub to zone out to 'my happy place', where ever it is!
