pressure

I haven't told anyone that me and my partner are TTC but my partner has told so many of his friends even though I asked him not to at the start. As far as I know 3 of his friends know but I believe it's more than that. I now feel under pressure to get pregnant. I keep thinking that there going to think there is something wrong with me as I'm not pregnant yet. I feel really let down by him. Like it's our thing. I wanted it to just be between us. Am I over reacting and being selfish or do I have a right to be upset?
