What could be the reason for unusual period and late period

Me and my husband have been trying to have another baby. This month my period was 7days late and since my son was born 14 months ago my period has been on the same day almost every month if it late or early it was only by one day. My period this month has been very light witch is unusual today is day 3 of my period and this morning there was only a spot on my tampon witch isnt normal im unusual bleeding pretty hard still on day 3. Im not sure if im pregant and maybe having a miscarriage or what it could be can anyone give me there ideas or if theyve had the same experience please and thank you for your time

Ask doctor, but you may be pregnant!! If so, congratulations!!

Even I think that you should consult with your gynecologist about this, as irregular periods between menstrual days can be a serious issue, it's better that you cure it on time, you may also try menstrual cups during your periods, so that you are comfortable during those days.
