I read your post in the one thread and the answer to your question is can you get pregnant after an abortion and the answer is yes. I t won't prevent you from getting pregnant. But trying to hard could prevent from getting pregnant.
With my daughter the only symptom I had were bad headaches. I don't ever really get them so I knew that was one. Of course now that I have 2 kids and a husband I get them more lol...
But now with my son, I think I had every symptom a pregnant woman could have. Every pregnancy may not be the same as others but he best thing to do is wait and see if you start your period or just take a hpt.
Good luck :d
