Hi! so i had protected sex 4 weeks ago today, and when the guy ejaculated, a little bit squirted out on my pelvic area but not inside my vagina. my period was supposed to come a week later, but it never came. i took a test and it came up negative. but my period finally came 2 weeks after and it was pretty heavy. i just finished a few days ago, but i am still having cramps, along with not much of an appetite and i have been feeling tired. i was curious if there is a possibility i am pregnant? or am i just freaking myself out and the symptoms could be due to something else?
