We are trying to conceive from last 3 months. Before that she had regular 30 day cycle. But after starting intercourse, the menses cycle reduced to 27-28 days. For last 3 months she have some symptoms like breast pain, diarrhea and constipation, Gassy feel, back pain etc. So we will expect a baby. But at last it will end in a menses. Can you please let me know why it happening and give me a solution please.
