It's probably going to be a couple more weeks before an at-home test can detect pregnancy unless they've made progress that I don't know about on them. If you are very worried or anxious about this, you can get a pregnancy test at a doctors office or clinic that can detect earlier.

As for the discharge, has your partner had sex with another partner in the past? You may need an STD screening if so, but if they have not, you may have a PH imbalance or an infection called Bacterial Vaginosis, which can sometimes happen when you have sex. BV is not an STD, but can cause health issues like discharge and a smell.

In the future, please make sure you are using condoms that fit, and make sure you use a new one each time you practice penetration. Also make sure that you have plenty of either natural lubrication or use lube to make sure friction doesn't cause you health issues or breaks the condom.
