Ovulated 2 days 24th - 25th!!

I ovulated Monday 24th -25th this month. Very dark lines. Had sex mostly last week following up to ovulation and after. Feeling cramping ever since monday and going to the toilet now and then. Not due my period till the 8th Oct and I'm 3 DPO

Anyone else the same as me or been through this and found out they where pregnant?
