Hey all ! need some advice I feel as tho my periods have gotten super short I ovulated super late this cycle which was cd21 which was a Thursday  5th I'm normally 28 to 30 day cycle it was due on a Thursday the 12and didn't show its face till Sunday 15 which was cd 31 by the next day it was done completely! I even put my finger up there clean fingerslol tmi sorry but I had what looked like brown old blood I'm wiping and I'll have very very lights pink only when I wipe but that just lasted till today i had AF like cramps all through out the week after I ovulated.. I'm not saying I'm pregnant .. Because I would feel symptoms I have back aches and pinching feelings I've taken pregnancy tests negative ..called my fertility doctor and they said it sounds like implantation ? I used one tampon !! That Sunday ! And that's that but it looked like a normal period but with pink and browny coloured blood with some red too my concern is what if my periods are getting shorter what should I do my fertility doc wants me on bc  for a month to regulate my cycle again I've never ever been on bc But before I do anything my husband who's a nurse is telling me to wait cause he thinks I implanted .. How long after would you wait after bleeding ?  I was told 10 days I feel I should have had something by now I'm getting nothing but a clear negative ! If I was pregnant I would have had something by now in my theory ? I don't know .. And if my periods are getting shorter is there anything other then bc ? I work out 3 x a week or sometimes 2 x a week I eat healthy I just don't know why I went from so regular to irregular like this ? Help!!!! 😫😫
