My wired period

This is TMI.

Me and my husband had sex on 10/6 using per-seed. This is our 2nd time using it. 1st time was fine but the 2nd time blood came out with it. Now I’m on a period. My period comes whenever it wants to and I don’t know when I ovulate. When will be the best to try for a baby? We been trying for about 2yrs
