I'm sure the doctor will tell you if you need to take a break from ttc. But I can see where your dh would be concerned.
Cysts....ugh. Yes, all women get them. We produce them as our follicles (eggs) mature. Once one is mature enough to be fertilized, the cyst ruptures releasing the mature follicle (ovulation). (this cyst is called a luteal or functional cyst) Then the cyst remains in order to produce progesterone (the hormone responsible for our raised temp after ovulation as well as all our pms symptoms) And the cyst will remain after an egg is fertilized in order to produce the hormones needed to sustain a pregnancy (hense the nasty 1st trimester). They are completely normal/natural and will not cause a problem with conceiving.After the egg is release and NOT fertilized or does not implant, the body reobsorbs the cyst (which is why your temp falls) and you start your period.
However, not everyone's body works that way. (Take me for example) Sometimes, your body doesn't get the message that there is no pregnancy, or it does get the message....and just doesn't care. And it does NOT reobsorb the cyst. This will cause a delayed luteal phase and thus postpone your period. Normally your temp will stay elavated. And you will need meds to 'restart' your cycle.
Sometimes, when you don't reobsorb the cyst, they continue to grow. This can cause a lot of pain (That's ME!!)
*And then there is PCOS (poly-cystic-ovarian-syndrom) This is when the body produces multiple cysts. This can and will prevent ovulation (thus pregnancy) However, I'm not well informed on this condition and I'm not sure why it happens (actually, I'm not sure anyone knows why it happens).
Anyway, sorry for the book. Did it make sence?
