Oh sweetie, I'm sorry you're feeling so upset! I can relate, though. I actually had a miscarriage in December and now this time around, everything puts me on edge. I've had a bit of a pink tinge after lots of pushing to try to have a BM and its kept me awake for hours, worrying. I tried to start back up running, and then had one small incidence where I wiped a small amount of bright red blood. I actually stopped breathing for awhile, I was so terrified. Once the constipation went away or I stopped running, so did the pink/bright red blood. Cramping still happens, but it's truly related to gas/needing to poo, for lack of a better way to put it. I ASSURE you that what you're experiencing is perfectly common and not something to overthink, though I know that's impossible being in your shoes! Everything in your body is much more sensitive now that you're pregnant, lovely. Deep breaths. Massive hugs. May the rest of your pregnancy be happy and healthy.
