+ OPK on CD 9 (after Chemical)- when to BD?

[JessinChi]

I am kind of confused at the moment. Last cycle (our first TTC), I had a chemical. I started bleeding 9 days ago. We got the go ahead to continue to TTC this cycle. Yesterday I started taking IC OPKS (wandflo) as I have heard that ovulation can be unpredictable after a chemical. Yesterday there was barely a second line, so I assumed O was far off (I have a fade in-out pattern). Tonight, I had an extremely strong second line, almost identical to the control line (possible sligggghtly lighter, but not really).

Here's my dilemma- my husband is currently working a 6 hours drive away. He will be home in exactly 45 hours. If we wait for him to come back, are we totally going to miss the potentially fertile period?!? There's a chance he could come back tomorrow night (in 30 hours) but it would mean him driving 6 hours after a full day of work, getting home at 1AM, and then BDing (how romantic is that?).

Edited to add: I chart my temps too, and normally have a dip the day before ovulation- my temp actually went up today! Are my hormones just out of whack?!

I am so confused- I usually ovulated on CD 13 at the EARLIEST, and my CM pattern has been a little off. I usually have a couple of days of EWCM before O, and haven't noticed any. Any input or experiences are much appreciated!!!
