As in the other question. . .weeks ago I had light nausea and stomach aches they stopped. I was worried cuz I've been havin unprotected sex with my bf. Now. . .I've recently got few cramps but they went away but last month. . .I had my period in the beginnin of the month for a week 2 days go by n I got it again for a week. N we've still had unprotected sex and this month. . .I've already missd. Idk if its cuz last month havin 2 or any other reason. Should I b worried? Idk what I should do if I should wait another month

If you have missed this month's period, try a pregnancy test. One of the bleeds you had last month may have been a period, but the other would not have been, so you had some irregular bleeding for some reason.
If you get a negative result, see what happens next month when your period would be due.
