Period

D ✨ • Twenties, law student, London, UK
Hello ladies,
My Mother Nature arrived yesterday, before glow was telling me that was suppose to come on the 26 once that last month came 2 days earlier.
Was kind of spotting yesterday, kind of. Today when I woke up my pad was full and then I changed. 
The second one was half full so I decided to change and until now, looks like it is spotting.
Being honest I'm worried that I do have any kind of sickness.
On the last months my period doesn't come as much as used to come, for example before January.
I noticed as well that my nails are quite fragile, I've been drinking a lot of milk and I thought was because of that, but being honest, I don't know and I'm scared.
Did any of you passed for something like that? 
I'd like to hear what do you think or something like that.
Thank you xx
