Weird periods

Chuchu

Hey ladies I’ve been a bit worried about what’s happening to me maybe you guys can help me figure it out ? So I’ve been having weird periods for 3 months this being the 3rd I have very regular periods and usually always on the date my calendar says it’s my first period day but since ive been trying for a baby 4 months ago and still trying I’ve started taking prenatal vitamins and omega 3 and in August my period started changing ,it was slightly brownish and light flow but for 3 days than in September my period came a few days early I even thought I was pregnant but negative pregnancy test prove I’m not I had spotting for 2 days than bright red for 2 days but light flow and 2 days brownish flow Also light and now this month according to my Calender I was 4 days late than yesterday the spotting brownish very light brown started around 13 am and that was it nothing more for the rest of the day. Today I woke up and also didn’t get anything around 10 am I had spotting again and again around 15 (this are the times I’ve checked for differences in color etc ) and it was like a faded red with a slight yellow undertone and a very light flow more of a spotting has yet filled my pad or is even close, can anyone help me understand what’s happening or if anyone else has been experiencing the same thing, I have had all my check ups did ultra sounds and everything to check my fertility status and it’s good I just have a few ovarian cysts by my gynecologist said it’s nothing to worry about so why is it hard to conceive ?
