4weeks: Symptoms of early pregnany

I don't really know how to date the pregnancy yet, but I read in forums that the day of the blood test is considered as 4 weeks preggies.  The preggie symptoms seem to have intensified, and I was hoping for more relaxed days.

• Burping - started on 10 Mar, which is about a week ago.  Would suddenly have to get up from my sleep just to burp and then go back to sleep.
• Frequent peeing -  also started on 10 Mar.  I just kept wanting to pee even though there isn't much to pee.  Now I pee like twice in an hour in the day and wake up about 2-4 times in the night.
• A little breathless - Seems to happen in the bathroom after a bath.  Just feels very stuffy and breathless.
• Bloating - started about 15 Mar.  It was clear that I was bloated when I couldn't wear my shorts once again.  You can see the pictures below for comparison.  The left photo was taken on 2 days back while the right photo was taken after all OHSS symptoms were gone.  But the bloating is not as bad as the OHSS experience.
• Nausea - also started about 15 Mar.  Possibly caused by the bloating.  The bloated tummy was just uncomfortably.  At times, I just couldn't sleep cos the tummy was in the way.
• Loss in appetite - Possibly another side effect from the bloating.  Couldn't squeeze in much food.  Had to nibble every hour.  It took me 3 hours to finish a tub of KFC mashed potato.  I ate not because I am hungry, but more of a self-assurance cos it is weird not be eating so little.
• Gastric attack - Possibly because of the drop in appetite.  I had my 1st gastric attack on 16 Mar at 5am.  Quickly ate half a slice of bread and drank gaviscon.  Had to sleep sitting up and finally the gastric subsided.  Coincidentally, gaviscon also reduced the bloating and I finally felt hungry for lunch.  Could eat a little more which felt really good.  But the bloating worsened again that evening.  I didn't want to keep relying on gaviscon for the bloating so I am tolerating the discomfort until the next gastric attacks.

My plan for the symptoms - going to visit my TCM doc as usual.  Hopefully she can have some remedy for it.  Else I will wait til my first scan and doctor's visit on 26 Mar for more advice.
