Daughter's first period - normal?

[DesiccatedCoconut]

My daughter, aged 12 and a half, started her period yesterday - I think. Not unexpected at all - she has had all the other signs of puberty for a couple of years. She went to the loo and called me up as there was blood. Apologies if TMI: it was quite mucous-y, but the blood was quite red. Since then, there's been only an extremely negligible bit of rust-colour on the pads. She was also feeling sick - nauseated - beforehand, and then proceeded to vomit fairly profusely around 20 minutes after she went to the loo. No cramps or any other type of pain. She's been more or less fine since, if a tiny bit wobbly.

Am I right in assuming that this was in fact her period? I'm working on the assumption that anything goes when it's the first time and that everything's "normal". When I started around the same age, I had no vomiting and it lasted fairly steadily and heavily for about a week and it wasn't mucous-y. I'm sure it's fine, but just looking for reassurance, I suppose.

Thanks in advance!

Yes, you are right. I recall mine being exactly this way when it happened & then nothing for another four or so months.

I really hope this isn't the same but I had similar with my then 12 year old DD.

Long story short it wasn't a period at all - it was Inflammatory bowel disease but she didn't realise the blood was coming from the back.

It took four weeks of telephone consultations with the GP ( Covid times ), a misdiagnosis by an A&E Dr ( who told us it was a period and not to worry ) and finally an emergency admission to hospital as her body was gradually shutting down after four weeks of bleeding and vomiting before we got the treatment she needed.

As I said I really hope this ain't the case for your DD.

Did not mean to write ain't! No idea how that happened.

Yes, I think that's probably about right, I remember mine being similar. There was nothing then for about 3 months, and then there was, well, everything!

Yes, she's started.
In my early teens I sometimes vomited (and had diarrhoea) on the first day; it's not unusual. Prostaglandin hormone effect. Just reassure her it's perfectly normal and doesn't last long.

yes - i remember my first one. 2nd one was something else (vom)!

My daughter is the same age. She had her first in August. Very similar to your daughter's. Then nothing until this January
