Period while pregnant

Anyone ever get there period and he find out they are pregnant?? Just curious my period was a little weird .. I usually cramp bad in which I did but my period was shorter and def lighter usually I pass clots like crazy and this time I passed one literally could use 2 tampons for a whole day.. It was also shorter then usual...and now my nipples are all veined which is weird for me I'm sure I'm just being retarded but any input on it would do!! Thanks ladies
