My period is two days late and my boobs aren't tender like they usually are. I take birth control pills but I took it late two times this month. Meaning, I forgot to take it in the evening and took it in the morning. I don't forget too often but when I have before, it hasn't resulted in pregnancy. Anyways, I bought digital pregnancy test, read the instructions, and got an error message from both after taking them. I'm going to go buy the non digital ones and try that. Has this happened to anyone? I thought I would take a test, get a negative result, and be relieved. Now I'm really scared since over the error messages.
