I have just been through an Follicle stimulating hormone (FSH) treatment with a last injection of luteinizing hormone (LH) to cause ovulation and it is supposed that last Monday I have ovulated and of course we have had intercourse on the "right times" to finally achieve a pregnancy.
According to my doctor. Monday I was supposed to be fertile, we have had adequate intercourse in order to get pregnant an now (Friday, actually since yesterday) I feel veeeeeeeery tired, I am hungry (my stomach makes noises) but at the same time I feel disgusted to food, if I eat I feel like vomiting (I haven't done it) and sometimes I feel dizzy (just as if the floor moved).
I would like to say that these are early-pregnancy-symptoms but I don't dare to. Sometimes I think that everything is product of my imagination.
My question is, can this be real?... is it possible to start feeling something like this in so short period of time?

I was on fertility drugs and was watched closely. I went to the dr every week and I found out I was pregnant less than a week after I was. The next week I was feeling it already. So personally by 2 weeks I was feeling like that.
It's hard when you are t.t.c and cant, you dont want to get your hopes up but hard not to as well.
I would say you have a great chance to be pregnant w/ those symptoms. I was sick from 2 weeks until I was done giving birth (not to scare you) just so you know. So personally yes it is very possible.

I planned my conception out in great detail and I felt ODD, not quite myself, within 3-4 days afterwards. I KNEW in my bones that I was pregnant. I know this seems silly. But, I had the nauseated feeling and smells started to bother me. I think some women JUST KNOW when they conceive. I was all excited and took a pregnancy test too early and it came back negative. I KNEW that was wrong. So, I waited until 2 days before my period and retested...POSITIVE!!! Hubby and I were thrilled. So, yes, this can be real for you. I believe some women just KNOW. Good luck!!!!!!

you will hear stories from people stating they felt when the concieved, it may be a aide effect of the hormones (been there done that) try to relax you will be checked in a few days, they could be signs but I have been in your shoes and you want it so bad that your body may be reacting this way. to be really honest 4 to 5 weeks of pregnancy is when you notice the symptoms real early signs are just about the same as starting your period but you will feel more tired then usual.

I don't want to sound bad, but don't get your hoipes up yet. You could very well want to be pregnant so bad that your psyching yourself into feeling it. Or maybe you got pregnant last month and didn't realize it. The thing is I have been pregnant 4 times and the very earliest I had symptoms was 3 weeks in.

Take a deep breath and just wait and see. I know it's maddening, but hey you'll have 9 months to be excited and the rest of your life to raise your child. Good luck!!!
