Weird cramps...very nervous

Joelene
Hey ladies, I'm 9 w 3days. This morning hubby and I had sex.nothing strenuous but straight away after I had some cramps in my upper abdomen. Almost like gas pains....I've literally sat down most of the evening but they are still there esp when I get up or stretch to get something.no bleeding and they aren't heavy enough to make me stop in my tracks but they just haven't left. Anyone had anything similar or can shed some light!? Was absolutely fine this morning just came after sex which is odd xxxx
