Please help!

Hi ladies, I thought I was a pro at tracking having been ttc for nearly 3 years, but this cycle - I'm confused! I'm calender day 13 today and the last two days I've been having really strong opks but not quite positive. However, hardly any EWCM. Extremely painful O pains all day yesterday. This morning, opk is basically non-existent in terms of a line, I have loads of EWCM but my boobs are a bit sore, which only happens after O! Only had the chance to DTD Sunday night and hopefully tonight. Worried I've messed it up again!
