Advice Needed

Hello ladies ...

I am a 25 year old whom has been suffering a while with severe period issues .. last year I had a constant period for 6 months ... I was on tranasanic acid and utovlan ... think that's how it's spelt ... I was also on the injection for over 4 years and this is what had resulted in all these problems .. I went to see the gnaenocologist and he told me to simply switch contraception .. I'm now taking the pill ... but now I'm having three periods in one month ... me and my partner also want to start conceiving soon however my app is telling me I'm not fertile ... any advice ?
