New to group

Tati

Hello ladies im new to the group- me and my fiancé have been trying to conceive since November. This is my first month missing my period (first time ever missing my period) Im currently 9 days past due.... i have taken 3 pregnancy text all different days but they are negative. Is this normal? Should i be worried? I cramp every now and then im hungry often than usual and i feel nauseous on some days and have headaches..... any feedback or advise would be greatly appreciated.... oh i was going to wait to see if i came on in June to call the doctor not sure if that’s a good idea..... thanks for all the feedback in advance
