Had sex on second last day of her period, we realized the condom broke after we finished. A week later she had a period which she said was heavy that lasted only 3 days. She has been having many of the early pregnancy symptoms including nausea, threw up twice (once 2 weeks after sex and once 4 weeks after), frequent urination, breast tenderness. She has had back pain in the middle of her back and upper back. Currently it is about 4 weeks after sex and she had a fever of 101 for a day, has the chills and is extremely achey all over. I am very confused, we thought we were fine once she had her period but she has been having lots of symptoms since and now it seems like flu symptoms. Please help!
