HELP! CM changes OMG

Dunno if this is in the right place...

Right, i cannot believe that i am even having to consider this....

Molly Jane is 2mths old, i have had no AF yet...
She has started sleeping through the night this week (8.30am-5 or 6am)
She is totally BF
anyway, DH and I DTD the other day (no contraception - thought that we would be right :doh:) and that evening i noticed CM changes, initially i thought nothing of it, but later i rememebered that CM changes are to do with your cycle (obviously we did not have to 'try' long for MJ as i dont know all the ins and outs).
CM that evening was thin and stringy, egg whiteish... this means ovulation right???? :confused:

Oh i feel so stupid, can someone tell me if CM changes happen post pg that are not related to ovulation???

I cant believe this OMG OMG OMG
