panicking 😩

Im 6 months pp with two girls. Im done having kids. Im not on bc it doesn’t act right with me it makes me miserable and mean. We do the condom thing. But of course my app says im 27% chance of getting pregnant today and my husband came on to me sooo hard tonight he wouldn’t let me refuse. Soo for about 20 mins I said no no no and then finally gave in 😩 he put it in a few times without a condom and then I refused to do anymore with out. How worried do I have to be with precum. Im literally panicking never again. Even tho it feels so much better 😩😭😩😭
