Kind of a long post! Sorry!

So my fiancé and I have been ttc for a year and 4 months now. We are 21,so young and overall healthy. At first we didn’t keep track of anything, thinking it’ll happen and be easy. But man were we wrong. After not getting any positive tests, I finally started tracking my periods better and ovulation. After that didn’t work, I bought ovulation tests to make sure I was ovulating. And making sure we BD on the right days. Still didnt work, so tried preseed. Ive also been taking prenatals, stopped drinking alcohol at some point and drinking more water. STILL NOTHING. So I finally decide it is time to see a doctor and get help. I was very scared and it did take me awhile to get the guts to make an appt. but I finally did it. I was nervous at first. As the appt. day got closer, the happier and more excited I was. Thinking that I can finally get on track to figuring out why we haven’t concieved. Especially since I have regular periods and I ovulate every month. Well I went in and filled out all the papers. All the information. And when they called me back the doctor asked me the same questions that was on the paper I had already filled out. I spoke to her about my really bad period cramps that I get. They are really bad and I’ve even visited the ER cause how much pain I was in. And all she said was I’m young and healthy and should have no problem. Not even to worry about my cramps. She did a Pap smear and was sending me on my way saying keep trying. So I said again even with how bad my cramps are, trying to say like that can’t be normal? When she finally said she will schedule an ultrasound to make sure. But like it’s nothing. I felt and still feel so defeated. Like I wasn’t really helped. And I expected a few blood tests and a little more worry. I mean nothing crazy just basic stuff. I just wanted some answers. Sorry for the long post just looking for some feedback and if how I feel is wrong? Am I overreacting?
