Have i testes to early?

Amy

Hi guys im no expert on ttc, ovulation dates etc so looking for advice i got a possitive ovulation test fri 2nd feb so 2 weeks tomo .. i have a long cycle so will be due period 20-22nd feb .. last 3 days ive had mild cramping, serious tiredness, very little appetite, lower achy back and just feeling slugish today i feel this sharp just not painful feeling low done right hand side .. i done a test this morning and it was negative could it be to early? I no period sysmptons are similar but thought it to early for period symptoms as i dnt usually get them till 2-3 days before.. any advice would be good 😘
