I've always had irregular periods due to anemia,so it's never been uncommon for me to go a few months [even a whole year!] with no period.So I thought nothing of it when I went to my doc in Otc. of '01 with so odd pains right below my ribs.She felt around some,took a pee sample,and guess what?I was 7 months preg! Had #1 in Dec. of '01.But with #2 I felt the typical preg symptoms within the first 2 weeks [I know b/c the "surprise" that #1 gave me,I immediately went to tracking all forms of "wifely duties" immediately after birth of him].With #1 I wasn't ever nautious,light-headed,swollen,etc.,I felt great,even rode our motorcycle the whole first 7 months![Until we found out,ofcourse.]But with #2 I knew immediately,not only b/c I had been writing it all on the calendar,but b/c I was a little bloated feeling,nautious everyday,my smelling was super-sensitive;all the classic signs.And when I took a test by week 2 of this,it was pos.!So you might be!Good luck!
Don't know what your infertility probs were,but I was told at 12 that I'd never concieve,or carry a child due to severe build-up of scar tissue in my uterus from repeated self-healed fibroids.But guess what....2 kids later,and I'm pretty darn fertile!
So whatever your problems are,I hope you get what you want!
