Ok so we've been trying to get pregnant. We already have 2 boys, so I'm praying for a girl. Since nov 2009 I was on the mirena, I had it removed in jan 2011. So since then.
So all the months we've been trying this month is where I feel pregnant.
-my nails started growing last month-strange to us, I can grow my nails for the life of me
-i look like I'm between 4-5 months pregnant
-my breasts are bigger and tender
-peeing a lot
-feel little movements-fluttering
-hungry all the time-for certain foods
-headaches
-feel sick at night
-cant sleep on my stomach anymore
-constipation
-increase of discharge
-acne
-for 2 days my heal hurt and then the next day my whole leg

My periods have been weird lately too.
June I was late 4 days--period came but lighter than usual
July I was 6 days late-spotting, medium and 2 days spotting
Aug-1 day early- light- not usual
Sept- 2 days early-medium then 3 days spotting--then 2 days later spotting only 2 days
Oct- on time but it was light and orange,next day then pink, next day med red, next day red/pink and then pink spotting.
I have pain on my left side, my ovary I think.
Ive done pregnancy tests this whole time and their all negative. Not sure what's going on. I'm going to need to make a doctors appt... any ideas

You said it yourself... time to make a doctor's appointment and see what is going on. In the meantime, be sure to treat yourself as if you are pregnant while trying to conceive. Prenatal vitamins, healthy lifestyle choices, etc.. Good luck!
