Had sex on ovulation day got my period two weeks after period spotting and cramps?

Not pregnant: If you got your period two weeks after ovulation, you are not likely pregnant. You need to understand that, even when everything is just right, there is only a 25% chance of getting pregnant each month you try. That's just nature. Keep trying. The more you try, the more likely you will conceive.

If you had your: actual period 2 weeks after sexual intercourse then you are not pregnant. But if you are not sure if this is your period (i.e. spotting) then would go ahead and take a home pregnancy test. Take care.

Period: Ovulation occurs about 14 days before the next menstrual cycle so your cycle came exactly on time. If you are trying to get pregnant then you will simply continue the efforts next month. If you want to avoid pregnancy consider starting birth control
