They can not start before implanation because the body does not produce any hcg until implantation occurs.
It is the hcg that causes the initial symptoms.

You can feel psuedo symptoms that come from your own anxiety/excitement/hope/fear that you maybe pregnant.

Also many pre-menstrual symptoms are very similar to pregnancy symptoms it's just that because of your anxiety/excitement/hope/fear you notice them more or are more senstive to them then you usually are.

The first 12 weeks are subject to nausea because the placenta has not yet fully developed and so your body is making the hormones.
By week 12 the placenta has usually fully developed and it takes over the hormone production instead fo your body. So typically women start to feel better at this point.

There are some women who continue to have nausea and/or vomitting through their whole pregnancy.

Thank you for your info. I'm not really having the symptoms yet, other than my left breast's nipple is just a little sore, but like you said, it might be because i'm getting a little more excited. I don't usually get those symptoms when my period comes, but the body is a weird machine... It can definitely play little tricks on your mind sometimes

thank you for your input.

With my first pregnancy (i was 18 ) I didn't have a clue that i'd even has sex (i drugged with rohypnol) so when I skipped a period and got serious vomitting in the mornings I figured something was wrong, took a test and got a positive. I didn't have fatigue or sore achy boobs, just sick morning, noon and night.


With my last (viable) pregnancy (i was 25) I got a positive test the day my period was due and my symptoms kicked in about 3 or 4 days later.


I got home from work, took my bra off and almost yelled in pain.

For about 2 maybe 3 weeks I had incredible fatigue - i'd get up eat breakfast and be ready to go back to bed, and at the same time I had achy sore boobs. I mean they were ok while I was up and wearing a bra but as soon as I took it off it was like "wow ouch"

i didn't get any sickness or nausea until my uterus ruptured.

I also had incredible heartburn.


With both my ectopic pregnancy and a non viable pregnancy (blighted ovum) I did not have any nausea, fatigue, achy boobs or anything.

... What a story! I'm so sorry to hear about your first pregnancy. I can't imagine how you must of felt. And all that pain you went through with your second one... Wow! I can't wait for all those "awesome" symptoms! He he he.

thank you for sharing your story with me. It means a lot!

The biggest things for me too was sore boobs, morning sickness, and extreme fatigue. I'd struggle all day with nausea and it's a weird kind of nausea. It's nothing i've ever felt before. Certain foods really made me sick just to look at them like mushrooms, steaks, and fast food. I just wanted fruits and crackers. Then when i'd take my bra off to take a shower i'd want to die my boobs hurt soooo bad. The fatigue was extreme too. My day would end when i'd get home from work at about 3:30. I'd go straight to bed and only get up to eat and shower. If I couldn't nap i'd be in bed for 7 and be very grouchy until then. It was so bad. It all started at 5 1/2 weeks -- one day after I got a positive preg. Test. The fatigue and morning sickness ended around 14 weeks. The boobs kept hurting until about 20 something weeks. They don't hurt anymore, they just leak like crazy.
Good luck to you! I really hope it happens soon!
