OMG i am suffering from the same thing, i am having my 2nd child now!! Very excited!!
With my 1st(Bethany) i had loads of sickness, nose bleeds, fainting...the works!! This one feels completely different, i have cramps all the time, i feel depressed & my poor partner can not do anything for me!!

I have also had so much time off work because i feel exhausted & now worrying about my job!
I really know how u feel, I thought the 2nd one was supposed to be easier?? lol
Hope u feel better soon & congrats! XX
