Before I got married, my menstrual cycle was 28days and I m hardly ever late. Now it s about 2 months into my marriage. In that month, my period came 2days earlier (I attributed that to our honeymoon trip to Dubai). The next month, my period came 3days late and now it s coming 4days late, accompanied by severe cramps and burning sensation in my upper abdomen and chest . Does that mean that my cycle has changed. We are trying to conceive. I m 26 and he is 36. I ve never been on birth control pills.
