Delayed period for 2to4 days coming first as pink drops then stops for 2 days then comes normally flowing red with clots. Am I facing any problems?

Weird cycle. It is important to not panic just because one cycle if a little off from the others. The main issue to track the pattern over time. If your cycles return to normal over the next few months then one abnormal cycle is not an issue. Always make sure your pregnancy test is negative. If you are not on birth control consider starting which will also give you better cycle control.
