Thanks for writing in.
If you have been taking pills earlier and also use condoms regularly, there is no need to worry about pregnancy
even if you took a break last time.
Sometimes the body tries to balance the hormones and this may be the reason of your light flow.
There can be other causes of decreased flow also like anemia
Please consult your gynecologist if you feel you feel you are excessively tired and weak.
Doing a pregnancy test is not an absolute essential but you could do the home pregnancy test for peace of mind.
Hope this helps.
