Hey i cam sympathise. i was properly broody from the age of 15, it came and went a little but at times i was so broody my whole body ached. I couldn't really describe other than that-a need to be a mother and have a baby.
No one else really got it at the time, my mum woudl just say go and have fun and enjoy yourself (which i did, but boy was it hard waiting!).
I had to live with my broodyness for around 12 years!Looking back i don't know how i did it, but i did as i wanted everything to be as i wanted it first. I think the hardest time was when i was actually TTC, as i was then 'allowed' to get pregnant, but didn't straight away ahhhh.
Anyhoo, i understand what it is like, it's so hard-but when the time comes, God how you'll appreciate it and enjoy it and be proud that you waited sooooo patiently. in the meantime throw yourself into wedding planning, ooh and i would start recording my cycles-tho i guess your prob doing that already x
