Feeling generally crap

Rainbow
I'm 6wk+2 after an early miscarriage on the 29th Feb. I have the usual sore boobs and mild cramps but I also have lower back pain on one side, headaches and just generally feeling a bit crappy. I appreciate this is probably normal (no bleeding so far) but I can't help worrying. I've started getting teary and emotional. I've had to tell my boss already because I work in a lab, and I'm terrified I've jinxed myself 😢
Anybody else feeling this way and/or having silly irrational thoughts? Xx
