Egg Fertilization

[Lexima]

This is something that keeps bothering me every month:
Even before I started taking fert. meds my bbs start to hurt about 3 days after O.  It has been happening for as long as I can remember.  Now that I'm paying attention to every little detail, does this mean that egg was not fertilized in those first few days after O, and AF is coming?

But I also had situations where bbs started to hurt even before O.  On the other hand I think only twice in my life I haven't had any bb pain before O, or some that started few days before AF.

Did anyone do any research on this?

I'm feeling much better now at least I'll know now that it doesn't mean much.

My bbs are usually sore before AF comes although not lately.  A nurse once told me that it may be related to coffee driking.  Go figure!  Like ff says, it means nothing...

Yeah, I would also get sore bbs right after o until AF arrived. That is, until I had my last miscarriage. For some reason, I haven't had that the last three months. No idea why, because I know I ovulated all three months (blood test one of the months, and doing OPKs and BBT charting all three months).

But, anyway, I've had two miscarriages, and both times I got pregnant, my breasts were tender as usual after ovulation, but then gradually got much more sore as the luteal phase progressed. Combined with some mild cramping, that was my one big "sign"!

Good luck this cycle!

Thanks I'm feeling slightly better.  Also found the following on ff site:
Tender Breasts: While your experience may be different, you may notice a pattern to the sensitivity of your breasts. They may feel more sensitive at around the time of ovulation and they may continue to feel sensitive throughout your luteal phase. Again, if you notice that there is an observable pattern to the sensitivity of your breasts, it is useful to record it in the checklist on the data entry page so that you can make future predictions or notice changes from cycle to cycle. While some women say that tender breasts are an early pregnancy symptom, there is no way to know if you are pregnant by the sensitivity of your breasts. Breast sensitivity may be linked to increased progesterone. Progesterone is increased both during the luteal phase of your menstrual cycle when you are not pregnant and during pregnancy. The sensitivity of your breasts may be useful for you to cross-check other signs if you have a consistent pattern but it is not a useful fertility sign on its own.

I may be wrong about this but I think that your body doesn't know about fertilization until implantation takes place around 6-12 dpo.  At implantation your corpus luteum gets a signal to produce hormones, etc.  So I don't think you should worry about that.
