Trying for children

Hi everyone I'm not sure if this is the right page to be posting on sorry if it isn't....
I have been 4 months now and Iv been tracking my ovulation and doing everything by the book vitamins included and nothing's happening everyone around me is getting pregnant or having babies and it feels like torture to me 😞 Iv only had a period in May and an extra long one in June I had no period  at all in July then one day and a bit beginning of August none of this makes sense to me And all I'm getting is negative tests I just want a baby of my own 😢 can anyone help?
