Help ? Unsure ?

Fiona
Hi everyone . 
Ok so I had my first period last month after coming off the pill 5 months ago. 
So it's been 34 days since last period and unsure really what my cycle is really . When i was on the pill I was always 28 cycle . 
Me and my husbound are trying for a baby . And don't know if I should take a test to see if am pregnant , or wait another week . 
For the last 3 days iv had really milky white discharge not loads but a little bit every day .. 
Any advise would be great . :) 
Just don't know what to do ?? 😬
