Birth control issues

K

I just started birth control at the end of May. I am on the lowest dosage you can get of Lo Loesterin fe. I have recently started getting headaches quite often and sometimes I have weird cramps that I’m not sure if they are in my reproductive system or stomach aches. I haven’t been having sex but I have been intimate in other ways with my SO. I always get nervous because the headaches and stomachs aches and unusual discharge instead of a period. It always scare me thinking I’m pregnant(even though I know it’s practically impossible) I’ve even taken a few test to be sure. I have a doctors appointment soon and I’m unsure if I should ask my doctor for something different or what. I don’t like the anxiety and headaches I’ve been feeling ( I think it’s related to the BC. What would you all suggest?
