Hey XxCalxX,
What a shame the ‘family planning clinic’ lady was so unhelpful. Even though you have had a few tests that have come back negative, it would still be worth you calling the number Meg11 listed above. The free ultrasound that you could get at a pregnancy centre would be great to confirm whether or not you are pregnant. You have a pretty pronounced bump there!
Do you have someone you can talk to about your concerns, someone who could go to the pregnancy centre or doctor with you?
