Early pregnancy sex ?

Jasmine

I just found out last Friday that I am pregnant! Great news wonderful okay….. now to get down to the nitty gritty. I am about 5 and a half weeks. I feel fine far as nausea. Super fatigued and bloated but good for the most part. I’ve been having very vivid sexual dreams which I heard is pretty common. A friend of mine said if I have sex this early it can cause a miscarriage. Is this true? Just want to be safe. Thanks.
