Hi,
you should see your Ob & Gyn.
You might just be having
Braxton Hicks contractions - but you shouldn`t be showing any signs of blood (brown stuff o the toilet paper).
Your
cervix might be operning -
unless you had an examination today - which might then be a slight show of blood from the examination.
If not - go to the doctors and get it checked!
alls the best!
Kind regards,
JR
