I got my second implant on October 18 the first one was taken out and the second was immediately put in. My doctor said there were no restrictions, so I thought that meant I was protected immediately from getting pregnant. But I wasn't on my period when I got the second one out in and every where I have read says wait 7 days before having unprotected sex after getting the implant but it doesn't anything about getting another put in right away. And I haven't had a period since October so I just need to know if it's because of my birth control or if I could be pregnant. And also because of the hormones from the implant it makes tests read negative no matter what. So I'm really worried. Please help!
