Ok this is my short story to help you understand what I'm trying to ask. I am 23 years old. I have 3 children 1 passed away due to SIDS. My husband and I decided for me to get an IUD. It has been in for a year now. I have had normal periods until now. Lately I spot a brown colored blood for a day two at most. This has happened for my last two periods. I also have gained about 10 pounds in the last month! I have changed my eating habits started exercising and taking natural diet pills and just keep gaining!! I don't understand it. We don't use protection since I have and IUD. My belly doesn't look fatty it looks like a baby belly. My weight gain is only my belly and breast. I took a home pregnancy test and it was negative. Which when I was pregnant with 2 of my children I had negative results until I had a blood test done. I don't understand what's going on. I don't have medical insurance and cant afford to go to a doctor so I am puzzled and at a stand still. If anyone has any ideas on what's wrong or what to do PLEASE let me know.
