Thanks for writing to us.
You are suffering from irregular period with red brown spotting
& clots now.
There are several reasons to be ruled out like early implantation
bleeding (due to irregular taking OCP with unprotected sex), mental stress, thyroid problem, hormonal
imbalance, emotional upset, wt gain/ loss etc.
In this case, I suggest to do one home pregnancy
test or blood test
for beta-hcg to exclude pregnancy. USG lower abdomen, LH/FSH, Thyroid profile etc may be needed to rule out underlying pathology if pregnancy test is negative. After that, you should consult with your gynecologist.
Avoid stress, control body wt, take healthy diet, practice safe sex with condom or OCP in regular manner, maintain personal hygiene and sleep properly.
Be well and take care.
