<s>[INST] I lost a baby over 5months ago now, but had my first depo injection 3months ago. Since the same day of the depo I have spotted blood some little some more heavy but only spotting. It made me sick to the point I couldn t eat without being sick etc and I always bleed during sex. My injection is due to run out. From the last time I had sex though the spotting has stopped completely and now I am constantly needing the toilet. My lower tummy the muscles feel like I have a pins and needles sensation especially underneath my belly button. Is it possible I may be pregnant? I have red many forums though that women of all ages have said it messes up the body and can give you fake symptoms of all kinds. Would you be able to shed some light on this please? [/INST] Hello, Depot shot is very much effective in preventing unwanted pregnancy and to be taken once in 3 months. It has failure rate less than 0.3 per HWY. But there has several side effects like irregular period/ spotting including long time amenorrhea, prolonged infertility after discontinuation, wt change, headache, abdominal discomfort etc. You may do a USG lower abdomen, thyroid profile, LH/FSH to rule out underlying pathology if any. Consult with your doctor and take suggestive measures. Take Tab Chat Doctor.  Avoid stress, take healthy diet,  </s>
