What do you think the likelihood is?

What's the likelihood I will become pregnant this month? Here's the background info:

Had a long drawn out miscarriage that lasted from August 19th to September 25th.

I began using ovulation tests last week. I had low-no LH surge on Wednesday the 11th and 12th didn't test Friday or Saturday. Tested Sunday and Monday which had a high LH surge. We did the deed in the 12,lth, 14th, 15th, and 16th.

My AF started on 10/29 and had heavier bleeding than i normally have in the beginning then had spotting from then on...

You think it's just a fluke or could it happen?
