Ovulation and Discharge..

Can you still be pregnant and ovulate after conceiving? I had discharge that was like a booger...stringy and clear and thicker. Is that the end of ovulation? If I had it..does that mean I'm not pregnant? Ttc and on the second month. Or do you get that discharge when pregnant? I remember having it before but idk if I was pregnant or not...it was a long time ago. Thanks for helping!
