Pregnancy Info HOME

Hello everyone! I had my first child, a daughter, 12 weeks ago. and i br___tfed for about a month and a half and then switched to formula....I have still yet to get my period and i was wondering if this is normal? almost 2 weeks ago i had some brown spotting for about a day and a half but thats it and i'm beginning to worry that i could possibly be pregnant again....the past couple of days i've been getting headaches, tiredness, and my br___t have become very full and heavy feeling. also, my nipple became sore about 5 days ago and it lasted only a few days but these are all symptoms of pregnancy as well as pms, so i'm just wondering if anyone gets these symptoms for pms, and if i could get pregnant so soon after having my first chilld...thank you!! also ive been having muscle spasms in lower right abdomen and idk what it could be from?
