This happen to anyone

So my period was due Tuesday..I’ve taken two tests one Tuesday evening then one yesterday morning both negative...

Can I still be pregnant and not get a positive test right away?

I just want to know your stories of when you got your positives and if you got negatives first?

I must add I’m like clockwork when it comes to my periods I’m due on a certain day and will always come on between 6-10am😂

I’ve been feeling really tired lately and had some really small cramps that last seconds and when I cough I get these sharp pains..

Someone help me!!
