Something weird happened!?

Hey guys, 
I had a miscarriage in April and then had my period 25th may which lasted 6 days. 
I've been BD'ing every other day with my husband since 31st May and felt what I thought were ovulation pains relatively early on. 
I've been testing all the way through and not got a positive ovulation test so have been checking CM. Today and yesterday my CM fluid has been really dry and powdery (sorry TMI). 
Today (CD19) I got a really strong positive on ovulation test which I've not had as strong even when I was pregnant with my miscarriage - I know they pick up hcg levels too. 
What do you think? 
Do you think I could have ovulated early and have a bfp or do you think I ovulated late?
Because I fell pregnant the month after stopping BC pill I have no idea how long exactly my cycles are!
