22 Weeks tomorrow

I’d a bit of spotting this morning not much. Only once and hasn’t happened since. Have only felt baby girl move once or twice this morning and it’s not like her. And now have diarrhoea. I was at the doctor and he want me to go to the hospital. But I can’t for another 3 hours. I’ve to wait for my husband (we’re separated) to finish work for him to take the girls. He doesn’t think this baby is his so he’s in no hurry to help. I’m trying not to worry and think the worst but it’s hard.
