Ttc 30

I'm new to this group an I'm not 100% how it works do here goes, I've have two beautiful girls with my 1st she was a wonderful surprise, I was alot younger when having her which I was content on just her as 5 years went buy my partner an I decided to try for another this took two years for us to get a positive after having the little monkey we knew we wanted another but wanted to wait a couple of years, two years has now passed an still nothing, every month I'm gutted I get my period, thus month however I finished my cycle 3 weeks ago an I e started with brown mucus with a slight hint off pink blood only when I wipe, it lasted for about 4 days but not every time I went to the loo, also they was only pink a couple of time an I thought my period was coming its totally gone an I was wondering what this could be as I've not experienced this before, when I look it up it just say pregnancy or ovulation please help if anyone has experienced this an got a positive thanks xx
