Sounds like you're having a horrible time Everyone goes on about the second tri being great and makes it out to be symptom free, but I guess it must be individual... My MS finished early in 2nd tri and was replaced by daily headaches, which I found a small amount of caffeine (like 1 glass of coke or some tea) got rid of. Dr told me that minimal caffeine was ok, but different drs have different opinions! Panafon rapid also helped, but I found it made me burpy too, it must fizz in your stomach? Some people find fizzy/burpy things help with nausea though. I drank berocca in icy cold water to help with ms, check with a dr for that too, while berocca packets tell you it is safe, it may interact with other things that you take. Dizziness and feeling faint started around 28 weeks for me, and since then my blood pressure has been pretty low. A pharmacy should be able to check that for you. I found that I can't do the groceries on my own and things like the because I feel like I'll just pass out. I haven't yet though... Just sit when you need to and keep hydrated, dehydration causes all sorts of nasty symptoms. By this stage in pregnancy your blood volume has increased heaps, which can make you feel out of breath. Some sitting positions are more comfy than others for relieving that.

You sound pretty worried, and like its getting you down a bit, I'd see the dr anyway, it might just be normal pregnancy stuff but sometimes the reassurance is helpful, and if it is something more then you're onto it nice and early. I wondered why I seemed to be having such a yucky time of it when others glowed and felt great. Maybe we will be rewarded with babies that sleep well or something lol!

I hope you're feeling better soon so that you can enjoy your pregnancy, you're almost 2/3 of the way there now!
