Did I test too early? Could I be pregnant ?

Sara

Hey everyone we have been TTC for a couple of months and my period was due on the 28th . I took a test that day and negative then I decided to take one today but still negative & no period. My periods are always right on schedule . I just want a positive ...could I be pregnant? I have pms symptoms but not as extreme as I usually get them. Any info would be extremely helpful, I’ve been dealing with this “am I?” On my own because I want to surprise my husband!
