<s>[INST] i was fooling arnd with my bf on 23rd february. we were naked. but there was no penetration at all. no ejaculation either but some pre ejaculate myt have been there. it was not around the vagina though. i was due for periods on 2nd march. I am now 8 days late. I had taken a hpt on the 6th day after my missed period and it was negative. i have no other symptoms. im really stressed. my periods last month was also delayed by 5 days. im on medication for hypothyroidism fr the past 1 n half years. i am also overweight. please tell me what are the chances that i am pregnant? or is the stress keeping it away? [/INST] The chances that you are pregnant is virtually zero based on the information you provided in your question. The fact that you have a negative pregnancy test is also reassuring. It is much more likely at this point that your stress is contributing to keeping your period away. </s>
