I've been doing a little checking, and it is all starting to make sense. These symptoms started after the boys were born...

From Endo Resolved website:

The most common symptoms of Endometriosis are:

• Pain before and during periods (check-for about a week before I start)
• Pain with intercourse (no)
• General, chronic pelvic pain throughout the month (yes-thought it was due to the stim medication and/or their after effects)
• Low back pain (yep)
• Heavy and/or irregular periods (for the first few days it is heavy, but it is pretty regular)
• Painful bowel movements, especially during menstruation (um, yes...good Lord, yes. always during AF)
• Painful urination during menstruation (no, but could this be the "UTI" symptoms I just had?)
• Fatigue (always, but this could just be from life in general)
• Infertility (sadly)
• Diarrhoea or constipation (both, depending on the day)

Other symptoms which are common with Endometriosis include:

• Headaches (yes-for days before I start AF)
• Low grade fevers (have had them in the past)
• Depression (um?)
• Hypoglycaemia (low blood sugar) (not that I am aware of)
• Anxiety (who me?)
• Susceptibility to infections, allergies (as a matter of fact, I break out in hives pretty much every month as AF begins. lasts for a few days before leaving.)

I'm thinking this laparoscopy idea is a good thing.
