Scan worries

[ICantThinkOfAUsernameH]

Had a scan today (I'm only 4+6) due to health problems.
The sonographer asked do I have any abdo pain (which I do) and said I've free fluid? Have to come back in 2 weeks and see Dr today at 11am.
What's free fluid? Don't want to google.
Thanks :)

The most common reason would be an ovarian cyst that's burst.. But they will want to exclude other causes, such as retained blood from a previous failed conception or an ectopic... They'll want to check you out a bit more to see exactly what it is. The scan in two weeks will likely be to check up on the gestational sac itself - 4.6 is too early to see much but by 6 ish you can often see a heartbeat.

Free fluid is (unhelpfully, sorry) fluid that's not contained in a structure. So for example if you'd been in a car crash they might scan you to see if you were bleeding internally into your pelvis - that'd be one cause of free fluid (not the case here of course, I think you'd know about it if you had a broken pelvis ;) ) Things like burst cysts etc can be another source and are really common. I had a whacking great one that hurt like hell until it burst...

Ah thank you, that's really helpful.
Feel a lot more calm now!
