Am i pregnant?

So me and my partner have been trying to conceive for a couple of months and there was no luck. This month we decided to just take it as it comes and not think about it so much. My cycle is always around 27-28 days and has always been on time. Now my period is a week late and im on day cycle 34 which isnt normal for my body. About a week ago for a couple of days i had a pinch cramping lasting about 10 seconds a few times a day and throughout the night and this lasted for a few days. My CM has also been creamy white for a week now. My mother in law also mentioned she felt like i was pregnant. Could i be?
