im 5dpo and feel ok.....at least for now.....lol well during ovulation and after my body always feels off in some way....so for me its not unusual.....
At 3 or 4 DPO you really wouldn't be having symptoms unless you ovulated earlier than you thought. Implantation can happen at 4 DPO at the EARLIEST. But it's usually around day 5-7. Latest can be 12 I think? Your body doesn't start producing HCG (the hormone that makes most women feel pregnant) until implantation. Even then, it can take some time afterwards for the levels to be high enough to make you feel anything. Try to relax and find ways to distract yourself during your TWW! Baby dust to you, :)
