Opinions and advice needed

Ashley
I've been feeling kinda under the weather on and off for a week now. I'm 12dpo and I got a negative test yesterday.... on and off sore boobs, very fatigue, upset stomach, today I had some weird stomach feelings and if i ate my upset stomach would go away then come back. Headaches on and off some creamy discharge, mild cramping. Could I be pregnant and it's just not showing up yet? My cycle are irregular so no clue really as to when af will pay a visit but it's saying it should be here the 19th roughly. .. I've never really experienced pre period symptoms like this before either that or I've never noticed it this badly... maybe cause were trying to concieve I'm paying more attention.... any tips,advice, opinions are greatly appreciated
