When is it okay to have intercourse again after ectopic pregnancy?

ttc for rainbow baby • My husband and I have been together 7 years. Married since Aug 2014. We started ttc in July 15 and got pregnant first month and it ended in an ectopic. We are now waiting for our rainbow baby .
2 weeks ago I had emergency surgury to remove my right tube along with my 6 week baby. It was the hardest day of my life. I am getting over it, but want to be romantic with my husband so bad. It has been a month and a half since we have made love and it is driving me crazy!! My dr. Told me 4/5 weeks and it's so hard to wait!!! Anyone else go before that?
