vaginapagina | Pot interfearing with pregnancy test? (Reply)

So today my boyfriend and I had sex, we used a condom. However, I think there's a chance I may be pregant. I bit of his pre-cum got around my vaginal opening before he put the condom on. I got all of it off, but I'm not entirely sure if maybe a bit of it still got in there.

Today I'm going over my friends house and she's got some weed that we intend to smoke (this isn't a frequent occurance, this is the first time I've smoked in over a year and it probably won't happen again for a very long time after today.) My period is due in about 2 weeks, so if I don't get my period and I take a pregnancy test, will the marijuana interfear with that? Even though it'll be a couple weeks later? I know that pot sticks in your system..so that's why I'm wondering. Any information you guys could give me would be great! Thanks so much!
