Do I have a chance?

We weren’t trying this month due to a miscarriage at 6/7 weeks, we BD at 1/2am in the morning of 9th. I got a very positive OPK 10th and 11th.

I had a dull ache like the start of AF on the 10th I thought it could be ovulation.

However I’ve been using canesten BV treatment which says the environment isn’t suitable for sperm while using this,

Do I have a chance at all?
