I am 23. I did not fully have intercourse with a guy. The head of his penis did enter me a little and it was there for a little while. He went to the bathroom to ejaculate. So I know he didnt in me but could there be a possibility any could have got in? I am now more than id say a week and a half to 2 weeks past my period. I've had 2 pregnency tests both negetive. Urine tests actually. I have some simptoms not anything definite. I have headaches. I am on medications and when I dont take them I get these distinct headaches. Ive been on them and im getting them. Ive felt nauseated at times. Early in the morning and even in the evenings. Ive felt like at times I might start my period but nothing. I have never been this late in my life. Does anyone have any ideas. Plus im hungry alot. I do go tomorrow for a blood pregnency test to make sure but I wasnt sure if anyone might have some words of advice now. Thank you
