How long have you been trying? I think people think it's easy but it's really hard. It took me 8 months of trying before I got pregnant, then I had a miscarriage at 13 weeks. After another 4 months of trying, i'm now 5 weeks. Let's pray this one sticks.
What I did differently this last month was drink *a ton* of orange juice (for the folic acid) and lay on my stomach after sex (instead of my back, which is what I usually did). I don't know if these things helped but it is what I did differently and now i'm pregnant. :)
starting about 3 days after ovulation I started feeling these twinges in my lower abdomen on one side. After a few days it spread to my entire lower abdomen. Then after about a week it turned into a sharp throb that happened frequently but didn't last for more than a few seconds. I think this was implantation.
I also started having these crazy vivid dreams. I'd wake up confused or later in the day think back on something that I thought had really happened and then realize it was a dream. I'm still having those and I wish it would stop.
I also had dizzy spells/light headedness, increased hunger, sore throat, was thirsty a lot, no sex drive at all, fatigued... I think that's about it.
From all of that I just knew that I was pregnant and when I tested a few days before my period was due I got an extremely faint line (almost invisible). I tested every day after that and it got a little darker. Then I skipped 2 days and when it was officially 5 days past my missed period I got a line that couldn't have been any darker. I'm thrilled but scared because of my prior miscarriage.
So I hope this helped (sorry it's a novel!). Has your "period" ended? If so, you can test. Let me know what happens! Good luck!
