Well, the morning it happened, I got out of bed and felt a "pop" on my left side... it didn't occur to me at the time that that might have been my tube rupturing, but it did later. It hurt for a moment but I got up and went about my day. Later on that day I was feeling cramps just under my ribcage (below my armpit) and they were cramps like I'd never felt before. The cramping got worse and I started throwing up...
...unfortunately, there were no warning signs up to that point. My beta numbers didn't double properly the second time but had doubled sufficiently the third time so they didn't think twice about it. My prayers go out to you, sweets. It's a very scary thing to deal with when you don't have any warning...
