Help Bloody Colostrum !

Al

I’m currently 21 weeks & 3 days pregnant and My breasts have been leaking (no big deal they’ve been leaking since 15 weeks) but Sunday morning I woke up and the shirt I had on to sleep in had stains from leaking but it was bloody . Saturday night I had on a very tight fitting sports bra that I put on because my breasts started leaking to put on the breast pads the colostrum before putting on the bra was normal like always but I’m thinking maybe the super right bra put too much pressure on my breasts and clogged a milk duct in my breasts I’m not sure, has this happened to anyone ? I plan on calling my dr tomorrow since holiday is over and they will be open . Does anyone know if the tight bra could be a reason why or if this has happened to anyone before ?
