I had my son 4 months ago. I didn't get back on the pill for a month and now i'm on my 3rd month of pills and haven't really had a period. I still have so many pregnancy symptoms. I'm super emotional, hungry all the time, have cravings, tired (my son sleeps through the night) and super lazy. I have taken 3 pregnancy test over the last couple of months and they all come out negative. I'm wondering why I haven't had a period and if my symptoms are just still lingering from my sons birth in december.
