“Period” and Pregnant

Ok so I know you can’t actually get your period while you’re pregnant; however I do know that it’s possible to have monthly bleeding as I had 2 friends who experienced this like clockwork resulting in not finding out about their pregnancies until 6 or 7 months.

Anyway I said all that to say, today is the last day of what I believe to be my period. I became nauseous exactly one week before the bleeding started and still is so 2 weeks straight of it which is unusual. My “period” also came 4 days early which also an unusual thing, it was not regular but not light either I probably could have went all day before changing pads/tampons (of course I didn’t actually go all day without changing).

My question is have anyone here had that monthly bleeding or know of anyone who went through it?

What signs did they have that made them check for pregnancy?

When did they find out?

Also yes I am aware that no one here is a doctor I just want to know if there’s someone who’s been through it and can give me some ideas as to when I should take further steps as this is the first time my period has been different in 3 years.

P.S. Sorry if this isn’t the right group I’ve only been using for 4 months and not sure what questions go in which groups?
