I can't believe I'm typing this. I have endometriosis, PCOS, I'm 40 years old, gave up trying years ago. My ex resented me for having difficulty conceiving, I tried Clomid (despite ovulating regularly) which didn't work and messed with my hormones so badly it put me off the thought of ivf. We split. Life went on.
8 years later, I'm happily married with a teenage (only) child. DH not bothered about having children, we've never tried. He always said if it happened it would be great but if not, also great. Admittedly, we've never prevented either because I'm infertile, right? Years and years of no baby have proved this, surely at my age there's certainly no chance.
I thought I was perimenopausal. Endo symptoms have been worsening, I didn't feel well, thought I'd caught a cold or something. My pre-period spotting didn't happen, I waited and waited. I was at the surgery for something unrelated this morning and the nurse asked if I could be pregnant, I laughed as she handed me a pot to check. Dont know how she could tell but she asked me to go with her to watch the strip get dipped. Bfp 
I must have gone grey, she showed me to a chair.
Twelve years! Twelve! Spent my early/mid thirties in the infertility grieving process, years of stalking infertility boards, watching friends and colleagues have babies, experienced depression and anxiety, had surgeries, numerous invasive tests, had a breakdown, felt immense guilt at not being able to give DC a sibling, tried everything, every weird and wonderful trick and old wives' tale in the book. Life has moved on and NOW I get a bfp!
A mere month ago I started taking inositol again, not for fertility (see above, life has moved on) for sugar cravings and weight gain linked to insulin resistance. I accidentally bought the one with D chiro added, took it anyway. Is that what did it? Nothing else has changed except no sugar cravings. How can one dietary change like that deliver a bfp after over a decade? I'm dumbfounded.
DH is in shock. Not told the teen yet, not telling anyone yet. According to my last period it's very early so won't get ahead of myself, I know the stats at my age. It's going to take a while for this to sink in. Twelve years!
