12 week scan followed by spotting

Jenna
Hey all, had my scan on Monday which put me at 11w3 (roughly where I thought I was). I was so nervous about the scan I even had bad dreams about it! Anyway it turned out to be incredible- everything was spot on perfect!
Then yesterday I had some pink spotting - not huge amounts and thankfully nothing overnight but it's got me a little nervous. Have a complicated fertility history so called midwife who has booked me in for an EPAC appointment and scan tomorrow.
Has anyone else experienced this after a scan? It was an external abdominal scan - I wondered if it could be because they are pushing everything around? Baby was moving around lots which was amazing to see so taking that as a good sign!
