<s>[INST] i get sick to my stomach after eating at times and just out of the blue. And i have been eating a lot more than usual, i am on the birth control shot and my cycle is not normal so i spot a lot. I get sharp pains through my stomach once in a while, and in my privates after intercorse but i took a pregnancy test and it was negative. Is there a chance i could be pregnant? [/INST] hi,thank you for your query,the fact that you are experiencing irregular periods and spotting and also cramping is a sign of the side effects of the birth control.it means that your birth control method is not suited for you.these are not the signs of pregnancy.but still if you want to be sure,you can undergo a blood test.i would advise you to consult an OB/GYN to change your birth control method.thank you,wishing you good health </s>
