Is it possible to start feeling sick after eating in early stages of pregnancy? I'm extremely nauseous after breakfast and dinner especially. I'm only 7DPO.. I've also been napping more, if I don't get a chance to nap I over sleep my alarm and i don't go to bed late. I'm not sure, we have been trying extra hard this month and added preseed as well. Is it possible to feel like this before implantation or right after ?
