Hi, ive resisted posting on these TTC threads and tried to be 'relaxed' but I'm going out of my fecking mind! 
I am in my tww I think i felt nausea on the train yesterday after drinking coffee and the leaning of carraige etc and kept burping, I swear I've smelt things, and I can't isoloate where they are from (I do have an acute sense of smell anyway - but still think this has been increased even for me) I ve been feeling tired like in the drugged up sort of way but did have a busy week last week.
Ive just spent 30 minutes staring at ovulation calendars (comparing differing ones) and looking up stuff I know already, I feel nuts.
Right got that all off my (not sore booby) chest! 
I have calculated my cycle from 31st Jan as this was when the first smudge appeared, and started 'properly' the next day. Is this correct? Ive calculated all possible combinations of 27day cycle and 28 cycle and 31st/1st so due sunday/monday/tuesday.
I'm visiting my mum this week with DS(5) and fear its all I will be able to think about.
This is just the start,....This second child is overdue but have started to see befits of big gap etc and even if we just stick at one but then I am so broody...I want to have a BFP but I had an anxcious pregnancy last time and like Isaid this blood tww is just the start..
Is there anyone on here who dearly wants a child but is dreading the pregnancy well at least the first trimester - turing into a mushy mess, anxiety ridden, on doubtful days I question whether I am up to it all especially if Im having a day of mummy guilt re DS(5) for whatever reason....
How did they have babies in fields, you know at lucnhtime then got on with it. 
I am so
