Next time something like this happens go buy the morning after pill. It will bring on a period and end a brand new pregnancy. This only works the next morning and costs about $40 in the USA. It’s sold over the counter in pharmacies here. There is another set of pills (2), which can be used to terminate a pregnancy up until about the 9th week. This is called a medical abortion and can be ordered online if it’s legal to get an abortion where you live
