Is there still a possibility of conception?

Well I've been ttcing for a very long time and am having a lot of trouble pinpointing ovulation... This month I thought that I ovulated on monday, march 2nd, because I saw a lot of pink tinged egg white cm... we bd'ed on sunday so that would have been good timing if i ovulated the next day. Now I am second guessing it because even though my cervix was soft and open it was very low. A few days later on thursday march 5, I was still having alot of cm, and my cervix was higher but harder...I'm so confused as to when I actually ovulated. My last af started on feb 13 and I usually have about 33 day cycles but I have no clue how long my lp is and I think it changes all the time. Basically I just wanna know that this cycle wasn't a complete waste even though we only bd'ed on March 1st and late on thursday, march 5th.
