Hi hun
I posted the other day about endometriosis on health - I have stage 4 endometriosis and it's the most painful thing I know.
I've had one diagnostic laparoscopy and two treatment laseroscopies. The first was in 1999, the second in 2000, the third in 2002 and I had DS in April 2004 after 11 months ttc - I fell pg on my first cycle of clomid.
I also tri-cycled on the pill, which was OK. Periods were awful (even worse than off the pill), but only had four a year. But then I started to get cramp in my legs and migraines, so I came off the pill. Plus wanting to get pg and taking the pill aren't really compatible!
After my first laparoscopy in 1999, I took Provera, which turned me into a raging psycopath (I don't do too well with medicines...!) - I'd quite cheerfully have murdered people, but I was in too much pain from the operation (thank goodness - my only concern was I'd not have the strength to bury them in the back garden - scary scary stuff looking back on it now!).
I was also offered Zoladex, which is possibly the drug you've been told about that will stop your periods for six months. It puts your body into a reversible menopause. For some people it works brilliantly, but I knew that I was unlikely to be one of those given problems I'd had with meds in the past, so I decided not to take it. Plus my consultant lied when he told me there were 'no side-effects' - actually took my hand and promised me this(!) I'd done a lot of reading about my various options so I knew this was something I didn't want to try.
Before my second laparoscopy, my consultant (different man - got referred after the lies the first one told me!) said he hoped to give me five years clear of the disease. After the laparoscopy, he said he hoped he'd given me two years - I'd not been vocal enough about how painful it was and he'd found considerably more endometriosis and adhesions than he'd imagined would be there. I tend to put a brave face on things and make jokes when I'm in pain, which makes people think there's not much wrong! Stupid me!
So one month shy of two years later, I had my third operation - a lap and dye. He removed all the endo he could (there was a lot - I'm very good at growing it...) and found my tubes were clear.
So as soon as I'd recovered from the operation, we started ttc. Nine months later, I was rushed to hospital after an ovarian cyst burst (excrutiating agony - worse than standing on an upturned plug in bare feet 
- see what I mean about jokes...?!). I was scanned and found to have polycystic ovarian syndrome - hence my erratic cycle. I went back to my consultant and he said that I should try clomid and have follicle tracking to make sure I didn't produce 100 eggs.
On the first cycle, I produced one big fat egg and the lady doing the scan wasn't too hopeful of our chances of conceiving. I also had really bad ov pain - nearly put me off ttc that month! However, I'm very glad we did, because 9 months later, our beautiful DS was born.
He's now 8 months old and I've had two periods since having him (despite breastfeeding still) - the first was OK, the second was very painful.
So even with stage 4 endometriosis, bad adhesions and pcos, it is still possible to have a baby. I realise I'm one of the lucky ones and I hope it gives you hope that all the treatment and operations are worth it.
My surgeon was Mr Robert Richardson - he works from Chelsea & Westminster and (I think) Guildford and is superb.
HTH a bit - lots of babydust to you hun xxxxxx
