Coffee while pregnant

Hey all. I'm a ftm and am a bit cautious about things I do and what I eat, etc. I have always been a coffee drinker, not religiously or anything. But I do enjoy a good cup of coffee a few times during the week or when it's really necessary. I did stop drinking coffee all together once I found out I was pregnant because everywhere you turn someone is telling you not to do this or that and that caffeine is horrrrrrible. I am seriously jonesing for a GOOD cups of coffee and need to know if it's going to have any effect on the baby. I know once I start drinking it again it's going to become something I want more often. Help a sister out with some good advice! I'm almost 17 weeks along if that makes any difference. Nice people only. Thanks!
