Hi,
Welcome to ehealthforum.
The abnormal periods of this cycle could indicate a pregnancy. Some women tend to have period like bleeding at the scheduled period time during the first 3 months of their pregnancy. This happens due to the uterus still not being completely filled with the baby in the first 12 weeks time and there is normal endometrium (part of endometrial lining not involved in building placenta) still available to bleed during period time. After 12 weeks the baby fills the entire uterus so, there is no space for the normal decidua/endometrium to be shed.
In case you do not get your period this time properly, then visit your gynecologist and get a blood beta HCG level and an ultrasound scan done to confirm your pregnancy.
In case you are not found to be pregnant, then I would recommend both you and your partner to go ahead with the infertility work-up to see if any of you have any problems associated that is not allowing for conception. Start with treatment if indicated by the test results for aiding in getting you pregnant.
Take care.
