First Signs Of Pregnancy

I did a pregnancy test on the weekend. Came up negative. I havent had a period for a few months cuz I stopped taking the pill - my body was still re-adjusting etc.
(I came off the pill because doctor thought i was allergic to it - but i’m not)
I saw my doctor about it 3 weeks ago and he said thats quite normal and that i could go back on the pill again. Started back on it 3 weeks ago. But this week i’ve started to have some pregnancy symptoms. Sore/tingling breasts, light cramping (no spotting), one minute i’m starving - i eat and then feel really sick, loss of energy.
I have also had a bit of diarrhoea… has anyone experienced this in early pregnancy?
I know i may not be pregnant - but there is a possiblity that i am. Can anyone give me some advice or share their experiances? It will be much appreciated!
Thanx

After you ovulate, and say you are pregnant, how early do signs begin to appear? Are we talking several weeks or days after? The more specific the better please!

What are some of the signs and how pronounced were they at first?

i just want to know really early sings. burning nipples? stomach aches? but more detail.
i dont know if i’m pregnat and i’m still waiting so i can take a pregnancy test.

I have taken a few pregnancy tests but they are negative. I am experiencing some spotting after sex which is bright (fresh,new), I am unsure of what this could mean.

What do you feel first or what are the type of changes you go through?
