feeling pregnant then HEAVY bleeding a week late?

Chace

okay so while I was on vacation at the end of September and beginning of October with my husband my breasts were insanely sore like to the point where I couldn't wear a shirt and I had to heat a wet rag and place it on my chest forever. This went on for a little over a week and at work I had the worst pain in my breasts ever like sharp pulling pains from the top of my breast down.. (and I never ever get sore boobs, so this was new for me) so my husband and I thought that was a little suspicious and that I might be pregnant. well, time goes on and I get little twinges here and there around my stomach and i got the same crampy feeling i get when i ovulate.. i had awful heartburn that lasted a week and a half on and off, my appetite completely changed, my breasts were bigger and harder and sore, my back ached really badly (which yes, i know can also be a pms symptom), my moods were insane, i was so much more sensitive than usual, crying over everyday things that have never made me feel like crying before. we felt like I was just supposed to trust my body.. so we did and really believe im pregnant. my husband and I were just awaiting my period.. test after test was negative but my body was really telling me otherwise.. my husband and i both had the feeling that i was pregnant. and so we checked to see how far along i would be and started to track it. i downloaded glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> and had been tracking since about the day of my missed period. everything was going great! no period, still had all of the symptoms and now at 6 days late i started spotting later in the night it was light and i had some brown discharge so i thought okay this must be normal.. then the next day i had a crime scene (literally) amount of blood.. my flow is usually heavy but this was EXTREME, as were the cramps, they were terrible. i have never bled this much, sometimes the blood even looked blackish and with clots and i did pass tissue it was about an inch long and 5-6cm wide. and another about an inch long and 2cm wide. what i didnt understand was that the blood didnt seem like a period consistency, it seemed like if you were to have gotten a really bad wound. my husband and i though at first were really upset, after a while felt like everything was going to be okay. (my husband and i are very much believers in the holy spirit. and we felt God was telling us we're fine and to not worry about it.) well the bleeding seemed to slow down and the cramps were stopping. so we felt fine.. i took off work for the next day (today) and thought i would put myself on bed rest.. well today isnt any better and now the blood is more period like no cramps though.. im just worried.. i have read so many things about ectopic pregnancies and breakthrough bleeding and interuturine (?) fibroids and I dont know how to feel.. i would believe that its just my period coming a week late and just heavy as heck but the symptoms i had prevent me from fully believing that.. i guess all im asking for is people's similar stories and advice from anyone who might understand feeling pregnant and having every sign youre pregnant and then bleeding.. im just so confused and upset..i had awful heartburn that lasted for a week or two on and off,
