Denise

I’m 5 days late. Then again.y period has always been whacky so I’m not holding my breath. Took 2 pregnancy tests. One last night. One this morning BFN. BUT, my uterus. Very low abdomen has been...’vibrating? Almost like, champagne bubbles, or like a cell phone vibration. Lol. Idk. But has anyone experienced this?!
