Hello....weird question but...?

Well, if you are pregnant you should be careful having no matter what. It's not a great idea. But that is personal and completely your decision. I think the more important thing here is that you are in a unhappy relationship and you need to end it asap. I think you being so unhappy is what is making you want to sleep with someone else. You are not getting the love that you need from this person you are with now and you are looking for it. If I were you I would just worry about having a healthy baby and ending this relationship. Then you can move on with your life and someone else will come into it and you can be happy and feel that love that you are not getting anymore. Remember also that when you are pregnant you are much more emotional and you have needs. I don't really think what you need is to sleep with this person, I just think you need to find the right person. Hope I helped.
