about 10 days ago during sex the condom broke and me and my boyfriend were unaware and kept going, he came inside me and an hour after we bought plan b. I was ovulating at this time so I’m worried it did not work. I have been getting headaches, spotting, bloating, nausea and cramps. While some of these are plan b side effects they are also pregnancy symptoms. I just want to ask if anyone else has taken plan b and had the same side effects. We are really worried as we are young. I am also going on birth control soon, and just want to make sure it’s okay taking birth control soon after a plan b? How effective is plan b? I really need to know if I should be worried or not. I read that the bleeding could be implantation bleeding of an egg and sperm and I’ve been sick for days and very tired. Someone give me advice please!!
