AF is about 1 or 2 days late and I'm still getting a negative test ( dollar store test, haven't got a good one yet) but I have the following symptoms, please let me know if anyone who currently knows they are pregnant had the same symptoms during their 2ww :)

2. Increase gas 
3. Headache for a week straight 
4. Eyelids feel heavy/ tired 
5. Light watery cm day AF is due & day after
