Am I worrying for nothing??!

Right so I'm 16w6d with my first and I've had 2 scans where baby is fine and healthy 😊 but the past 3 weeks everyday I am worrying that something is wrong and it is really getting me down. I have another appointment later today but it's just to see a consultant (DVT history) and no scan. I have the growing belly and the leaky boobs 🙈 and the normal aches, but other than that I stress and worry that something isn't right.... Any other moms feel the same or am I worrying for nothing?
