Yes, approx 14 days- give or take 3 days -after period.

You conceived on or about june 13th....However it's not guaranteed.

On a 28 day cycle you're suppose to ovulate on the 14th day, although you may have ovulated sooner.
Considering the fact that you had sex with 2 partners that month your best bet is to have a dna test done. Nothing is 100%, but dna is pretty damn close.

I agree with michelle1981. You should've ovulated on or about the 13th - give or take a day or two. But I would also recommend a dna test just to be sure. If I had to guess i'd say it was guy #2 whos sperm fertilized your ovum:) hollie
