Am I being safe enough? (Avoiding pregnancy)

Ok before anyone roasts me I know it’s extremely unlikely. That I could get pregnant from this. I’m honestly extremely paranoid about pregnancy.

My period is like three days late, but my period is notorious for not being predictable. Also I’ve been under a lot of stress lately.

I’m not having sex. Me and my boyfriend do oral & grind. Are we being cautious enough?

He always goes down on me first. Before I go down on him. Whenever we grind I make him put on a condom. There’s was one time that he came on my stomach but ever since I’ve made him wear a condom. Am I being being safe enough?
