I actually had a period when i was about a month pregnant.I'm nearly 14 weeks now & everythings ok.It was almost like a normal period too ,just a bit shorter than usual.
Good luck hun,sending u sticky vibes.BTW i had a scan at 7 weeks 6 days & there was this tiny blobby shape,we could make out tiny buds for limbs & the spaces for the eyes but only by looking very hard,so don't freak when u don't think u can see anything as i don't think there is alot to see at that stage.
