This is my first time posting in here. i woke up the 17th of November with awful cramping and bleeding. I thought it was just my period since I was only 4 days late, decided to take a test and it was very faint but there was a line. I decided to rest that day and if I was still cramping and bleeding I would go in to the er the next day. Woke up the 18th feeling the same way. Went to the er my hcg was only at 29 so she figured I was miscarrying and that my levels should drop but to follow up with my primary to have them tested again. So I went to my primary on the 20th my hCG was at 56 so they wanted me to come back in a week and check again and to get in with an ob. So on the 26th I went it was at 535 and got in with an ob and he started me on progesterone and wanted me to come back on the 3rd. I did and my levels dropped to 325 so he said I was miscarrying and gave me the option to let my body do it naturally or have a D&C. I choose to let my body do it. Well here we are almost 6 weeks out my period has yet to return and we are so ready to try again but my body isn’t cooperating so I’m just upset and I’m so ready to be a mom and have my own baby. What do I do about my period? What’s the first step that I need to go in to get my body on track to have a baby.
