Possible first timer: is this cramping normal?

Hello! I'm 29 and my husband and I have been trying to re-conceive after losing our first baby at 6 weeks about 10 months ago... this month I am 3 days late, and I've been feeling a consistent cramping for about 5-7 days which have been slightly more intense in the past 3 days. It isn't like period cramps in that it doesn't leave and come back and it's not super crazy painful just like a consistent discomfort. Just want to know could this be it? I plan to take a test but am waiting a few days as I have taken tests too early before and been so disappointed 😩... my period is pretty consistent but was a day or 2 late the past 2 months so it's always a false alarm! Also my boobs hurts so bad I can barely move! Which I think is a good sign lol

Did anyone else get cramps like these?
