I've been using minoxidil for 4 months but I'm losing more hairs now. It is anything wrong?

It can take up to 6 months to see results with Minoxidil and there will be an increase in hair shedding when you first start using it. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options and any concerns you may have about side effects. There are great non-invasive options like prp/progesterone which work well with Minoxidil. See an expert. Best, Dr. Emer

A lot of people experience hair loss on the onset of Minoxidil.  You can consult with your doctor in looking into doing a few PRP hair treatments in combination with at-home cold laser.  A good Laser right now is LaserCap that uses 224 cold lasers and is FDA certified.

For the first few months it's common to experience some increased shedding while starting Minoxidil, so it may simply be an issue that will resolve itself in another few weeks. I would follow up with the doctor that prescribed it to you, just in case.
