 [ Symptoms ] 14 months after mirena removal still have irregular period cycles i had a completely cycle of mirena 5 years and had another placed for additional 18 months october of 2014 we decided to start trying again it is been 14 periods since then and my cycle varies 25  28 days long sometimes the cycles will regulate for a couple months and the next month will be a couple days short or a couple days late i am getting worried about not being able to get pregnant again is this normal someone on an iud for almost 7 years  thanks [ Disease ] this is a great question and i am glad you asked it not all medications are effective if dissolved in a liquid i would suggest you check with the child is doctor or pharmacist to learn if this technique is appropriate with the medication in question meanwhile i would recommend dissolving the medication in the smallest amount of liquid possible and having the child drink it all at once for example if you could dissolve the medication in an ounce or two of cola you could reward her with the remainder of the can after she drinks the portion containing the medicine dissolving the medication in a small amount of fluid will create a higher concentration of it in the mixture so that when she takes it she will get something close to the full dose i hope this helps
