I'm now 13 days late for my period I did two test last week and they was negative, but with my second wee of the day.. my cycle is always either 26 or 27 days, and now am on cycle day 40.. I rang my doctor to ask advice and she said to test again in a week which will be Wednesday so anyways I was impatient and tested with cheap ones called 1st aid pregnancy test.. this came out negative so my Oh as gone to tesco to pick me up clear blue digital which I will do Wednesday if that's negative I have a blood test booked for next week.. I know I can get pregnant because I suffered a miscarriage in January. I just don't know what's happening to me I'm not under stress or anything. Anyways I'm just wondering if any ladies on here have ever been in this situation and ended up been pregnant? Please don't read and run, all advice welcome 😘
