ok CD 1 is the first day of proper red bleeding, brown blood or spotting doesn't count, sorry!
A follicle is a little bubble of fluid on your ovary in which your egg matures and it literally pops out.(ovulation).
OPk's v HPT I think if you want a definitive answer you have to go with HPT, as an OPK could be either LH Surge or Pg.
I am too fascinated by the peeonastick site! Amazing what you can find out nowadays, in my parents day you waited two months before you were sure and then you handed in you urine sample to the doctor who sent it to a lab and they poured it on to the back of a frog!!!
My opk ((clearblue smileys!) I didn't go for the cheap option as really important I get it right and I don't use many.) says use early mornign urine, or not to pee for 4 hours before, which I haven't managed to do during the day since before I was PG with DS!!!
Willmouse get your doc to refer you to gynae. Is the blood bright red or brown? Would be more worried about red.
Mandy I would use them so you get to know when is a good time to........
MJIM I can't believe how pg you are this year has gone so quickly! Don't worry about the weight, especially if your midwife is not worried.
Love to everyone else will find out tomorrow what time transfer is.
