Since late last year, l have been complaining about my loss of appetite and consequently loss of weight?

I am a 43 year old Nigerian lady.l saw my menstruation on the 5th of this month February and now l saw it again yesterday being 19th February, meaning a 14days cycle which is quite absurd and unusual though no pain, flow is normal and reddish, no smell, just stupidly normal.

Since late last year, l have been complaining about my loss of appetite and consequently loss of weight. l used to weigh 105kg(not healthy l know) but now l have stayed on 95 since Dec. I do not have any accompanying sickness or illness except occasional itching in my private part which goes off after medication though my clitoris retain a pepperish pain(not unbearable though) but l just notice it all the same. Apart from that no other complain until this 14 days cycle stuff.

Last week Thursday, l bought a multi vitamin syrup to aid my appetite and so dont know if it has any thing to do with it(Protobex syrup)predigested protein fortified with vitamins, iron and zinc. I have a history of asthma and high blood pressure.l am daily on franol tablet and ventolin inhaler. What could be wrong please?
