Firstly, congratulations!! Ooh I remember my first pregnancy, it was an exciting yet confusing time
In regards to your bleeding, it does sounds OK, potentially it's just a bit of irritation. Also aches and cramps are also fairly usual and can last throughout your pregnancy ... or might not, it's different for every woman!
However if you are at all worried about anything, please don't hesitate to speak to your midwife. She is there to answer your questions, set your mind at ease and care for you during your pregnancy.
And if you haven't already, join in your due date thread, I always found reassurance talking about my pregnancy with other women who are at the same stage as I was.
All the best
