HELP...need an answer quick! Could I be pregnant?

22 & ttc. Has 1 4 year old! Been ttc for the last couple of mths, every since March to be exact! To predict my ovulation, all I use is the ovulation calculators & predictors. I mostly use mymonthlycycles.com or some other ones! I don't take my bbt or use OPK. I jus monitor my body. So, starting on june 19th or so, I was seeing white discharge but I don't play with it or anything to see if its EW type! So, from then on,dh & I bd on june 19th, 23, 26 & 25th! My lmp was june 2nd & my cycle is between 38-40 days but this month it was 38. The calculators that I use, some of them predicted I would ovulate June 23 to the 28 & ovulation will occur on the 26th but some said up until the 30th. I jus don't know anymore! But today is june 27th & I no longer have any white discharge. My question is : DID or was I ovulating & what could be the chances of me being preggo???????????
