Is this normal? Can anyone shed some light on this subject please. I'm exactly 5 weeks today and this is my first pregnancy and I seem to be worried and cautious about absolutely everything. The last few times I've had sex and I've had an orgasm and afterwards I've had cramps similar to a period pain (which I've read are normal) today I orgasmed and I didn't cramp at all. Is it normal to not have cramps after orgasming?
