Hi. If you think you are pregnant you should take a pregnancy test or consult with your doctor.

Not at all. Do you know the number of days in your average period cycle? Also, it has only been 29 days, so that’s not a long time at all.

I had my last period on 11st-15th of February and had unprotected sex from the 22nd-24th. Can I get pregnant my cycle is 35
I had my lmp on December 9th and it lasted 4 days. Had sex 12-30th of December basically almost daily through that time frame. When did I conceive? My baby measured a week ahead on March first so it doesn’t add up with my lmp ? Could I have conceived earlier?
Hi Ren. Your most probable days of conception are Dec 21-25 according to the information you gave. Did you ask your doctor for a conception date? What is your due date? You may have conceived earlier.
My period started on February 7 ended on the 14th of February when is my next period coming?
Hi Juliana, do you know the average number of period cycle for you?
Hi, i had unprotected sex on 2/28/16 and the pms calculator said my period was suppose to arrive on 3/12/16. It has now been six days and no show. I feel like it’s about to come on, slight cramping & some light white discharge. I also took a HPT which came out to be negative. Should i be concerned or wait another week??
Hi. Do you usually have irregular periods? The possibility of getting pregnant is always there when having unprotected sex, You may just be a little irregular. Give it a few days to see if your period shows. If not, take another test and contact your doctor if you have further concerns.
hi i took the morning after pills, my period is 5 days late. please am i pregnant
Hi, it’s common to get period late by 2-10 days because of morning after pills. Please wait one more week and then take a pregnancy test.
