Advice needed

My little girl, born July 4th (14 weeks old), is starting to be a little more emotional recently. She mainly wants to be held and if she gets put down so I can go do something really quick she starts to cry because I’m not around. Her dad works 12 AM to 12 PM so when he comes home he doesn’t spend much time with her before he goes to bed. Could it be that I’m spending to much time with her and she’s starting to get to attached to me? But also she has been drooling a lot, red checks and fist in her mouth recently so could it be possible she’s teething? Or not feeling well since the sickness is going around our area? Buttt this could all be totally normal as well. Help!! First time mom, don’t have much support from family or friends so this is my only way of help.

Thanks in advance (:
