I am asking a question! plz dont judge me.?

i am 19 years old and had with my bf about 2 weeks ago and i forgot to take my pill. ive been with him 2 years and i ALWAYS use protection im not stupid. but the one time we didnt i guess i was kinda strupid and 4t nothing would happen. but about 2 weeks ater i was sick 4 no reason and i was again about 4 days after that although i havent been sick atall lately?? the lower part of my stomack sometimes hurts but thats all really?
