<s>[INST] My husband and I are trying to conceive but I have had several 23 day cycles in a row. I gave up caffeine this month and I'm now on day 25 and I have not get gotten my period. Could this be the caffeine out of my system or should I test for pregnancy? [/INST] hi,       At the present, it is difficult to say whether you conceived or not.  In a 23 day cycle, delay by 2 days can not confirm pregnancy. wait for another week and test for urine HCG levels which may confirm your pregnancy.  all the best. </s>
