Okay so im 18. My periods are always on time. Last month me and my boyfriend had unprotected sex. We used the pull out method. My period never came. Now my boobs are majorly sore and growing , im moody , more tired than usual , bloating and gasy. I took 2 pregnancy test and both were negative. Now im having a cleary muscus like discharge(ovulation) Is ther anyway i may be pregnant?
