I ended my period on April 15th. I had sex unprotected and yes he came in me on the 17th, 18th, 22nd and 24th. It says starting with the 22nd I am fertile until ovulation day (27th). After the 22nd I started feeling more irritable, starving every 3 hours, queezy, and supppeeerrr tired. I literally feel like I need to sleep constantly. I don't know, this is just unlike me. I can smell everything and get slight heart burn here and there. I feel like I'm trippin because it's so soon. But I've read that it's possible and it happens more then you would think... can I get feedback please? This waiting 2 weeks thing is hard not knowing...

It is possible to feel implantation, which can feel like a very sharp period pain, lasts for a couple of hours and is accompanied by extreme tiredness. After that, you should feel relatively normal, not super tired or anything.

On my first pregnancy, I did know before my missed period, but it's hard to describe the feeling. I felt well and normal, but slightly hyped, and I felt a sort of ticking.

The super tired started around the second month, and the heartburn around the fourth.

If you are indeed pregnant, it is possible you became pregnant sooner than when you expected ovulation. It is quite possible to ovulate a bit earlier or later than the norm.

You can always try a test about 10 dpo and see what you get. The accuracy increases the closer you get to when your period would be due, but some women do get a very early positive result.

If you are hoping to be pregnant, it could also be that you are really looking for any possible sign... this is very common. Obviously you will have to give it a bit more time and see what you get when you test. If it is negative, wait until when your next period would be due and see what happens... test again if need be at that time. Good luck... hope it turns out how you would like it to!
