Hi. I was wondering if I had unprotected sex on March 25 but I got my depo shot on the 30 could I be pregnant?
The depo would not be able to protect you from pregnancy since you took it 5 days after you had sex. It’s difficult to determine if you’re pregnant based on the information provided..
I started my period on March 1st ended March 5th but on the 20th of March i started bleeding light brown off and on for about 5days my period was suppose to start March 28th But didn’t and April 6th I started bleeding light red with tiny cloths no pain and only enough to change a pad one time a day…i have not been on bc over 17yrs
Hello, please see a professional for this. All the best!
Hi, I have a 4 years old son..i had a miscarriage in 2013 but are still unsuccessful to conceive since then..i have a regular period cycle..every 30 days..5 days for each cycle..and because of that i haven’t consulted any doctor..i really want another baby..so have you got any suggestions that might help me? thank you.
Hi Liza, If you have already tried having intercourse on your most fertile days, then I think you should consult a doctor. If not, then please try it. Intercourse on a fertile day increases the chance of pregnancy by a big margin. For a 30 day cycle, your most fertile days will be day 15-17. All the very best!

Hi Mathew, please consult with a professional for this. We would like to help but without proper examinations and medical history, it’s not possible to know the reasons.

Hi Lisa, the possibility cannot be determined as such, but yes there are chances.

Hey.
Last time I had unprotected sex (pull-out method,and it worked for past 5months) on march 17th ,and my period started on march 13th..Few days ago I started experiencing my usual pms symptoms, and my periods aren’t always regular…I have breast pain (but slight), back pain but i also have frequent urination..if so, what are the chances for me to be pregnant?
Hi Angie, there is a chance of pregnancy yes. Please do not have unprotected sex until you are trying to get pregnant. Pull-out methods are not safe.
Pls if my cycle is 24/25 dayy, when is my fertile period and ovulation?
Hi Ogor, your fertile period will be day 09-12 and ovulation should be 10-11. All the best!
i had my last period on 29 to 31 of january 2016,i didn’t see my period in the month of February, I discovered i was pregnant in the month of march and I had an abortion on 10 of march 2016. when am i going to have my next period?
Hi Ruth, After an abortion, it might take 4-8 weeks easily for normal period to start. Also, after abortion, please wait at least for four weeks, do not have sex. Don’t even use tampons, use pads instead. Putting anything in vagina might cause infection.
My last day period was Mar 26, 2016 – we had sex on March 27 2016. Is it possible for me to get pregnant?
The chances of being pregnant would be low.
The first day of my last period was the 17th of feb… i think it lasted 4 days… i haven’t yet got my period but took a pregnancy test last week on Friday at about 10pm (I’ve been told morning is best, though) and it came out negative… any advice? Thanks
Hi Shavourne, pregnancy is not the only reason for late periods. A heavy exercise, a new medicine, or even a sudden change in diet can result in late period. Do you think any of these might be your reason?
Are you experiencing anything different too? Pain or allergy or anything unusual?
Hi, I had a miscarriage when my 1st son was 8 months old…that was in 2013. Since then I haven’t been successful in getting pregnant…I never consulted any doctor since I have a regular period. What advice could you give me? Please help. My son is turning 4 years old this year.
