strange question..feeling the womb/baby after sex

[mamaesi]

had an orgasm last night (easily thanks to pregnancy) and then it felt like my womb hardened and tightened...i could feel this big ball in my abdomen and it was strange

I am only 15 weeks. can you feel the womb from the outside at this point? anyone able to tell they have a baby in there at this early stage?

Sounds like Braxton Hicks to me. They're not always painful, especially not early on, and some women feel them, some don't.

You can certainly feel the womb from the outside this early on as I was measured at 15 weeks by the midwife.

All normal. That will happen every time you orgasm in pregnancy. The hard ball is exact shape of your womb as it tightens.
