Period 5days late have prego signs, stomach getting bigger. when i have to use the restroom and don't go stomach full on the lower part. what is this?

If you have been: sexually active - would go ahead and take home pregnancy test now. Take care.

Tough to say: The number one cause for a missed cycle is pregnancy, so if you are sexually active, check a pregnancy test. With your symptoms also, if they persist, then see your doctor form an evaluation. best wishes.

Time for imaging : Early preggo signs are incredibly vague. Some women "just know" but we have no solid clinical correlation to that. Also, there's very weak anecdotal evidence that stress (Constant "Am I possibly pregnant?") can throw your cycle off. Sounds like either bowel urgency & constipation, or urinary urgency w/ incomplete emptying, maybe UTI/cystitis, pelvic floor dysfunction or mass. Get CT or ultrasound
