Blood clot

Hi I wonder is someone had a similar situation. Trying to get pregnant for two months now. I’m three days away from my period but since last week had small amounts of pink and reddish blood when wipe. At same point they stopped and now they come back again but this time brown when I wipe and this when I wen to the toilet before even doing anything as soon as I sit. They don’t look like my normal clots of my period at all... The look is like small cells of something.

If someone with similar situation could give me a help.

thank you
