Advice??

Right ladies since being 14 weeks I no longer feel pregnant sickness has now stopped and feel fine I have no bump and have previously suffered anxiety so you can imagine what I'm going through over the last few hours I've been getting mild pain in my left side and low down in my vagina I even tried to find the baby heart beat with an app on my phone and failed I have picked it up before ?? am I just being paranoid and everything's probably OK?? I had my gender scan on Friday and see the midwife just before so either way I don't have long to wait but the suspense is killing me :(
