Bleeding at 12 weeks

Hi there, this is my first pregnancy and I'm at 12 weeks 5 days.
I've been sick since Monday with normal cold symptoms, on Tuesday things went from bad to worse with nausea (I haven't really had much nausea so far), dizziness/feeling faint, headache, loss of appetite, diarrhea and a really strong cough.

I woke up on Wednesday (yesterday) and went to the bathroom and found that I had been bleeding at night, it's brown blood and there's not a lot of it kind of like at the end of your period. I got really freaked out and moved my 12 week ultrasound from Thursday to Wednesday to make sure baby is okay, the scan showed the baby was fine with a heart beat and everything but still I was worried. I have a bit of pressure at the bottom of my belly as well and it's a bit tender. I've been feeling fine from Wednesday except for the cough.

I've been bleeding since Wednesday around 3am until now, is this normal? Neither my midwife nor the GP (the GP was useless!) seem to be concerned but I am very anxious and no one seems to be taking me seriously. I was hoping maybe some mums might have similar experiences and put my mind at ease because I feel like I'm going crazy.

Hi there. I have had spotting several times this pregnancy. Mine seems to be aggravated by tummy problems like constipation. In my first pregancy I also had it after diarrhoea, some people seem to have a sensitive cervix. It is a horrible feeling seeing blood. You are quite far on though and have recently seen baby so I think you are most likely fine. My midwife also told me that it is just one of those things that they can't really explain about pregnancy. Also, when I was bleeding I read a study that said that it was only once bleeding was more than a normal period that there was a strong link to bad outcomes. The pressure in your tummy could be from upset tummy/digestion troubles too maybe?
