Clomid and brown spooting

Flor

So ladies,i had my periods this month on the 15-th,and they just were 3 days,the third day was the last one(never so short. Ps: i had a mc on july). So i took clomid 2-6,and CD 11 i am supposed to check follicle and after that trigger shot. CD 6 evening i had intercourse. And the nex morning(today) i start spooting brown,mixet with pink diccharge.

What do you ladies think it is? Do i have to worry?
