Getting pregnant

The first time i got pregnant with my daughter it only took a month after unprotected sex to become pregnant. Me and my SO are trying for another child and I took an ovulation test and it said I was at my peak that day so we had sex and I got my period a few days later. This was last month, today I took another test and it says I'm at my peak again. Does that mean there's no way I can be pregnant ? Oh and I'm not expected to get my period for another 6 days.
