We have our first ultrasound on Thursday. I'll be 7 weeks then and I'm so nervous. I've been eating well, only drinking water, taking care of myself. But what if we don't see a heartbeat? I wouldn't know how to handle it. I've been feeling naseaus, way tired, high sex drive, 3 positive tests, acne, no period, no cramps, no spotting. But what if there's no heartbeat? I'm so nervous.
