Pregnancy sign/symptom????

Sydney
So I just woke up (shortly after having fallen asleep) due to a weird feeling in my tummy... Kinda thought period was coming but it felt different than normal... I usually know when my period is going to start by a feeling I get just before it shows up... When I get that feeling I go potty and it shows up... Anyways I went potty and nothing... Still feel a little weird... Anyone ever experience this and find out they're pregnant shortly after? AF due in 5 days.......... TTC #4 for a little over a year...
