Please ease my mind.....

My husband and I have had 2 losses since June and here I am 5 weeks along again. My first miscarriage in June, I felt totally fine but had days and days of pale pink spotting that I chucked up to normal, as we have 2 very happy, healthy girls. I never imagined hearing the words “there is no heartbeat and no growth after 5 weeks.” My second one was just in September and it was a chemical pregnancy, lost before AF was even due to come back. We succeeded again right away in October and in my heart I felt like this is the one, this is the one that’s going to stick around a full 9 months, I could just feel it.......however this past Thursday, on what marked my 5 weeks exactly, I once again noticed pale pink spotting that prompted me to force myself to use the bathroom a thousand more times (so it felt like anyway) and 800 of them times I still had the very light pink spotting. Friday and Saturday went by with no more. My hopes came back that 1 in so many women spot and have a super healthy pregnancy, so I’m one in that so many! Then today.......after a bit of a strenuous bm (sorry, TMI) I had pink spotting again. Went to the bathroom a few more times and still had it, but was done by the next hour. However about 5 hours after all that happened, I went to the bathroom again and had brown mucus discharge. My heart is broke as I prepare for the worst again. I have a 6 week ultrasound scheduled for this Friday and while I am hopeful and putting lots and lots of prayers up, I’m also prepared to hear the worst, well as prepared as one can be. Anyone have a similar story and end up having a healthy full term pregnancy?
