<s>[INST] I have the implanon in,  its been in almost 2.5 months. but im having such weird side effects. Identical to pregnancy. My lower stomach is so tight, which looks like an early pregnancy bulge. Nausea but no vomiting. I feel very full and can only eat very small amounts. Very thirsty. And tired to no end- even after 8.5 hrs sleep every night! My boobs get sharp pains in them and I have bright blue veins all over my body... Any ideas? [/INST] Hello, Thanks for choosing Chat Doctor for posting your query. I have gone through your question in detail and I can understand what you are going through. Yes implant being a hormonal medication can lead to this kind of problem. It causes increased acid secretion leading to the symptoms like bloating, pain in abdomen and chest, nausea and vomiting. You may discontinue the medication and shift to some other birth control option. Condom is one of the safest birth control option as it has no side effect. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you. In future if you wish to contact me directly, you can use the below-mentioned link:bit.ly/ Chat Doctor.  </s>
