Hi, I am currently TTC. My period is not due until Friday (four days away). Last Friday I started to get period pain style cramps which remained all day. That evening I had some really light spotting, which continued all weekend. I assumed from reading other posts that this was implantation bleeding? This morning I woke up and the cramping seems to be worse. It is now very uncomfortable and I am aware of it all the time. I have been peeing loads all weekend so I took a pregnancy test this morning just to check which came back negative, although ideally I should have waited until Friday before testing. Not sure if something is wrong? Should the cramping be this uncomfortable?
