How do I know the difference? Or what I'm having. I got a positive pregnancy test on December 27. Fast forward started bleeding last night it's only gotten worse, clots this morning. I was 5 weeks 1 day pregnant. I'm devastated as I was over the moon about being pregnant but I'm a firm believer in everything happens for a reason and that little babe wasn't meant for life on earth. I will ttc as soon as I can. But don't even know if this is just a late cycle, chemical pregnancy, full on miscarriage or what. I called the ob officer where I live but the nurses still haven't called me back. Any suggestions? Should I mark this as my period in the app? Any suggestions, or thoughts welcome while I wait.
