Questions

Okay so back in January I stopped using BC. I had two in one month and lot of pain. I finally got AF back at the beginning of July and tracked my ovulation and did the BD the day of and before I was suppose to ovulate. (There was a 33% chance) so anyways now I am 12 DPO and AF was suppose to start on Monday and now it's Thursday and still no sign but I have been cramping, and feeling nauseous for 5 days and one the second day I woke up with an extremely painful abdomen. As well as pains in my right hip.

So I was wondering if any of you think there is a chance or if it's just in my head. I've had no other signs beside that and being extremely tired and hungry.

I want to test but I don't want to get my hopes up again and buy more tests.

Can someone give me some insight?
