"My periods don't come at regular intervals every month. Last year in November, my period was expected to come on the 20th , but I mistakenly took Meftal Spas to reduce pain before my period, and it arrived on the 18th instead. Then, I didn't get my periods in December or January. I took a
pregnancy test, but the result was negative. This month, on February 13th, I had protected sex with my boyfriend, and since then, I've been experiencing mild cramps. Is this normal or a sign that my period is about to arrive?"
