When i was pregnant with Gabriel I had no desire to have sex at all, after he was born my libido seemed to shoot up, but now that i am pregnant again it doesn't even cross my mind, and i know that it is hard on my SO because like most guys i suppose it is a huge part of connecting with each other. Did anyone else have desire issues while pregnant or after and how did you deal with it?
That said, I would talk to your doctor about this. They've heard it all so don't be embarrassed. It could be hormonal, or just the way your body is.
