My AF  is two weeks late and I wouldn't say I had many pregnancy symptoms. I have had tingly feeling in nipples and a bit of backache and feeling a little tiered but that's it. I took a test which had the faintest blue cross and took another one on Thursday last week which was negative. I really don't know what's going on. My AF is always regular. Has anyone got any ideas or has gone through something similar ?? Any advice would be great.
