One does not get periods within days of ovulating. Ovulation happens almost 14 days prior to the next period. Therefore, if you are expecting your period tomorrow, you are unlikely to ovulate today. Hope I am clear to you.
I agree to your conscience that you must be taking the morning after pill or plan B
. Please take one to be safe.
The side effects of these pills are tender breasts, tiredness
but these last only for a short while. So, please go ahead and take one.
I hope this helps you. Take care!
