Is it possible to get pregnant and have your period? i ask because i am on my period but i have been really emotionally lately and my boobs are full

Period symptoms : Your symptoms are commonly associated with menses and are hormonally driven. If you are truly having a period you are by definition not pregnant. If these symptoms are recurring and/or bother you, consider getting on an oral contraceptive which has benefits of both regulating your hormones (and symptoms associated) and pregnancy prevention.
