Hey everyone..this is going to be a long post. Okay so i was late by 1 week and 1/2 on my period in june then got my period. July25 i started my period and it was til july 28 thats when i stopped which is unnormal for me because my period usually lasts 7-8days not 4. So Aug 4th i have light pink spotting more like discharge then on the 7 i had brownish pink light spotting(both were only when i wiped) then on the8th i woke up with my underwear not completly soked but almost with maroon colored blood i took a hpt and it was negative so i went to the ER and all they did was a uring pregnancy test and said they didnt know what was causing it and gave me pain medication. Ok so today its bright red when i wake up and heavy. Around lunch it lightened up then around 3 or 4 it lessend to just a drop when i wipe or pee. Im always tired i have severe hot flashes naseau sore boobs enlarged nipples and you can see my veins really well (i think ive went up a cup size) and ive gained weight also the inbetween my shoulderblades hurt really bad and also when i insert a tampon it is very painful. Ive been with my fiance 3 years and never had painful intercourse until july after my period. I know it isnt an std..(i have my ways of knowing). We are ttc and im healthy. So what could this be?? Im stressing here because im having all tail tail signs of pregnancy but im worried that im not going to be able to have children whatever is causing this can you give me some tips or tell me what it could be..
