Swaying girl timing ?

[Ttcnumero3]

Have 2 sons. Tcc a girl. Had mirena for last 4 years, taken out 2 weeks ago. no AF at all on mirena so I have NO IDEA what my cycle is/where I am. Have had very EWCM and cramping for 3 days stopping yesterday, today am watery and a little EWCM. Tested positive on opk tonight for first time (testing 2x a day). DD 2 nights ago, and 2 days before that.

Question is, should I DD tonight or hope that 2 day-ago sperm survive until I ovulate to increase chance of girl? Or for girl do you DD as soon as you get + opk result? Thanks!!
