Yes That's how I found out I was pregnant. I thought it was my period about to start but I just kept putting it off and one day I couldn't take the pain and sure enough doctor said "your pregnant" I was 3months pregnant and they said it was normal to have the pains It's just the pregnancy.
Its normal especially around the time your supposed to get your period
yes very normal. :) theyre light cramps not really heavy..
I am 4 weeks about to be 5 now.. congrat:)
