Thought I'd reply and update.
Well, It's now December and I still haven't had a period! I had my operation in July (2nd) and I bled from that day until the 20th July. Since then I've had nothing.
I'm wondering if it's now time to head back to the GP and ask for the hormone tests and double check of the thyroid they mentioned about a month ago when I told the GP about my lack of period after TL and D&C... I might do that just in case something is going on. I've also been insanely stressed out and never been off hormonal contraceptives unless trying to conceive so this is the longest time my body has gone with no chemical hormones...
I mean if this is normal, then I'm ok with it, but from what I've read... It's not quite typical, as you'd still get a period after both a tubal ligation and d and c. I'm petrified of going back to the gynaecologist just in case he wants to do another d&c or lap to check out what's going on. He wasn't gentle and healing after the operation absolutely sucked! Not to mention the weight I've stacked on since that time.
