Ok so i don't feel like it's possible that i could be pregnant bc my husband and I aren't intimate almost ever since we had our last baby 7 months ago. But I've been having crazy symptoms...like TERRIBLE lower back pain, ive been getting up to pee at least once or twice a night,(and I NEVER get up to pee at night.) and I've been crying at everything...literally, my son just rolled over for the first time today, and I bawled. the thing is, i took a dollar store test on saturday and it was negative....so what the heck? I'm on the pill, does it cause crazy hormone changes and peeing a lot and back pain???? or could i reallly be pregnant?
