I had an orgy...

So please don't judge. My husband and I have these friends(a couple) who wanted to have an orgy and we decided to do it. We were safe they went to the doctor, so did we... we are all clean and we ended up having a couple of drinks and then doing it. We didn't use protection but I'm the type of person that worries... I've been trying to get pregnant for a little less than a year now. But I don't know if I should take the morning after pill just to be safe. He didn't cum in me but I know pre cum can be a factor. But I'm afraid that if I take the morning after pill that the other times my husband and I had sex it could ruin those chances... I don't know what to do help please.
