Miscarriages

Well I ended up in the er last night from 12-5am . Unfortunately I had my 3rd miscarriage. I was supposed to be 11 weeks the baby measured at 6weeks6days. I didn't have any pain or bleeding until mon after my Bf and I had sex . I don't understand why it took so long for me to bleed and have pain if I lost my baby at 6 weeks. The Drs don't know why I keep miscarrying but they're gonna do some genetic testing to see what they can find . This is really heartbreaking for me I almost passed out in the hospital from crying to hard I have anxiety so I couldn't breathe this is probably the worst one for me 😖
