I think the Preseed is great. I didn't find it cold, but I think the box was placed in a warm spot in the house. I also didn't use very much (about 2mL, much less than the full applicator) so maybe that was why it wasn't very invasive
We won't be using it til Wed though (CD10) which is perhaps still a little early.
For some reason it's hard to find in Canada (I went to an actual fertility clinic to get it)
I looked up those CBFM's here and they cost $250 CDN from the drugstore!
I think I'll hold out for a while (and certainly shop around like on amazon if I ever want to get one!)
ADD10: There's so much information on this site for methods etc but it is a bit of a chore to search it all.
Here are the things I have learned for TTC :
1) Take a prenatal vitamin daily
2) Eat healthy and decrease caffeine, and really try to avoid alcohol completely
3) Drink lots of water (helps regulate so many things in the body (like pH) and create fertile CM)
4) Do the SMEP method : BD every other day from about CD8 through CD16 (and maybe an extra day when you know you've ovulated)
5) Use OPKs or a fertility monitor to determine when you ovulate (I haven't done this yet as I get sharp pains when I ovulate so I've trusted that so far, not that it's been successful for me... hmmm)
6) Use preseed sperm-friendly lubricant for BD time
I've also started taking "Evening Primrose Oil" capsules from CD1 to roughly ovulation time, then continuing with "Flaxseed Oil" capsules - it helps generate sperm-friendly CM and even if it doesn't help this cycle, it also has other helpful health benfits (in fact my DH was trying to get me to take Flaxseed oil a long time ago)
I'm the other very friendly ladies her have many other ideas too
Good luck
long post sorry!
