Thanks for your query.
You seem to be having breakthrough bleeding
PLease do not worry, as this is quite NORMAL with pills, particularly in initial months.
Continue taking the pills as recommended, do not skip any of them.
If the spotting continues, and does not stop within a couple of days, consult your healthcare provider, as you might require another brand with different ( slightly higher ) doses of estrogen
Remember to take the pills correctly at the same time everyday.
All the best.
