Possible plug at 33 weeks?

[boylovesgirl]

Hi ladies, I have a question that may be a little bit TMI but I am unsure if I should contact my midwife and wanted some other opinions. This morning I noticed a tiny bit (maybe the size of a small button) of mucus stuff the was streaked with blood. It's been about an hour and half and nothing more has happened. I have some small pains in my lower back but nothing regular or strong and my baby's movements seem normal. Is it worth calling their pager number or just wait until my appointment tomorrow? I goggled which was a bad idea as I am now worried about placenta previa/abruption. Thanks for reading.
