Am I ok?

My friend has a marijuana card and made some weed brownies. I didn't know this until I helped my self to one. I got a couple bites in and realized. I'm not pregnant but I'm ttc and I ovulated yesterday and we bd three times so there may be a forming baby in there. With this cause any issues implanting or anything? Please help :/ I've been having cramps but I was having them before the brownie too.
