Sex on early pregnacy

Okay! Im 7 weeks pregnant and my husband has been working out of state for one month and he is finally coming back next week! 😍 and I am so desperate to see him and you know, like ive been very horny ( crazy hormones lol ) but I dont know if I should have sex or not, I had a very slight spotting last week for one day and ive been also cramping a little... Any advice? Thank you all!! ☺️
