Crazy pregnancy story ! Twins ??

Where do I start .

First of all I had no idea I was pregnant . I found out in a & e . I was gushing out blood and clots and for sure thought something was really wrong with me .

Back track to April I took a pregnancy test

It was faintly positive and I didn't bleed in may so I thought I was pregnant , but as I continued to test the tests just kept getting lighter

This was one week later . I rung the doctors they were no help , I self diagnosed a chemical and waited to bleed , which I did .. in June (the 6th) I bled for ten days and just thought that it was over fast forward 19th June the first time I'd had sec Scince beginning of may , I started to heavily gush out blood after intercourse , took myself to a and e because the ammount was filling pads within the hour . They did a pregnancy test . It was positive. I couldn't believe it , I actually told them they must be wrong test again , they did via bloods and confirmed I was pregnant . Fast forward today I had a scan expecting to see nothing . You can imagine how I nearly fell off the bed when they said there was not one but two sacs .

All of this doesn't make sense to me but I'm back on Friday for a repeat scan ...

Any body can make sense of what has possibly happened .. maybe a missed miscarriage?
