Loosing hope...

My fiancé and I have been trying for a baby since about October... In November I had a bad hormonal imbalance that caused me to bleed for about 26-32 days... They started me on birth control which I had never been on before.. (I’m 20 years old) They recommended me to stay on it for 3 months which I did, my period wasn’t so long anymore, it was more normal... My periods have always been 3-4 days max for as long as I can remember.. Well my fiancé and I are pretty active, And I guess my body wasn’t used to it? I wasn’t so active with my previous partner.. anyway, We thought we were for sure Expecting this month because I had my “period” ends of Jan beginning of feb so like 31-3rd and my period just started yesterday on the 6th... I had crazy symptoms I was nauseous and having crazy cravings, sore breast, fatigue, and sensitive.. Well now I’m heartbroken all over again.. since My hormonal imbalance I started taking better care of myself. Like watching what I eat, and I even began exercising a lot more.

I’ve lost some weight but nothing to drastic, and I started taking PNs in January.. When I tried to talk to my doctor about me wanting to have a baby she looked at me like “why” she literally said “you’re too young why do you want to ruin it”....

I’ve always wanted to be a mom, I mean it’s something I dream about all the time, I’ve never been into the things girls my age are into, I’ve always been above my age group as in maturity wise, I’ve always wanted to start my family early.. my hubby has a child already, whom I love very much but I want to experience the whole pregnancy.. and My fiancé and I pray for babies..

I don’t know what to do...
