Think I am loosing my baby

So today I should be 10 weeks but yesterday I had some spotting in the evening and since then it’s been on and off. But now seems a bit more heavy. I have a scan booked in for tomorrow. But I feel like I already know what they are going to say. I had I miscarriage at 5 weeks in January, and one at 5 weeks in November. I thought this time this was it. I have been so sick with this pregnancy and so tired. But now I feel like it’s all come crushing down on me. I can’t let my other 2 children see me up set as they have no idea about the pregnancy, my partner is great as he is the only support I have got, my own mother don’t even know as we not spoken in over a year as she rather support my ex husband and his lies. I was scared but looking forward to this baby but now I just feel empty and alone. Don’t think I can try and do this again. 3 pregnancy’s in the last 5 months, think this is time to stop.
