Throwing up before AF due - very early symptom or am I deluded?

[Horispondle]

Have been TTC for 8 months and had 2 chemical miscarriages. In Dec/Jan we decided to stop thinking about it, only DTD when we felt like it and not pay any attention to cycle days. Have got a horrendous cough at the moment and it is making me throw up. I just think its weird that every time its been in the morning and feels like morning sickness. Have thrown up 5 out of the last 6 days. AF not due for another week yet.
Has anyone else actually been sick due to morning sickness before AF due? Is that actually possible?

No because AF not due for another week. my rational side is saying that if its too early to even take a test then this sickness can't be related to hormones yet?? I just wondered if anyone else thought they had symptoms very early?
