Depress and worried

Hi. I think I’m 3-4 months pregnant. Still haven’t seen obgyne because at first I was hesitant to continue this pregnancy. But with my husband support, were going to push through this pregnancy. Yes i know im sorry i was very hesitant and unsure having a baby at the young age. We’re going to see a obgyne this coming wednesday, im nervous, because i know its very late, im just eating healthy foods but i dont have the right vitamins for me and my baby during my 1st-3rd/4th month :( Im worried now plus i dont know how to shallow medicine. This is going to be hard :( Worried that our baby might have complications atm :(((
