I should be having my next period on 9 April is it safe for me to have sex 2-3 days before then?
It’s not impossible, but it is unlikely — especially if you have a regular, 28-day cycles. If your periods are irregular, however then it is harder to determine when you ovulate so it would be unsafe to have unprotected sex just before a period.
The first day of my last period was 5th April…I took a test today and it was negative but I am one day late. Could I be pregnant???
You took the test too early. You should wait at least one week after missing a period before you take the test.
Hi I have an average of a 30-day cycle. My last period was March 30, 2016 and I had sex from April 11 – April 17 (every other day). My Period Tracking App says I should be expecting a period on April 29 but I’m 4 days late. I took a test it was negative. What should I do? And yes it was a successful intercourse.
You’re testing too early. Wait at least one week after missing your period before you take a pregnancy test.
My last period was February 29 I have not yet seen it again what should I do?
There are a few critical questions that need to be answered. When was your period due? Have you take a pregnancy test? Do you have a regular or irregular menstrual cycle.
Miece and Ashley, yes both of you could be pregnant especially if you were intimate during your time of ovulation. Only time will tell. Even early detection pregnancy tests are sometimes inaccurate. Wait a good length of time before testing. I usually wait about 8/weeks after the first day of my last cycle. After having four children I notice the tests are more accurate the further away from my last period when I test.
Finished my period on 3rd april! When is the next flow! It started 29th of march
Hi, my period was April 3 and 6 and I had sex on April 11 .I want to know could I be pregnant or not?
It is possible that you did not conceive.
Sooo.. My husband and I had a little accident. Our car broke down and we got stuck out of town for the night. So we stayed with family that night. Long story short we ended up having unprotected sex. Btw i am very fertitle and so is he. We have two daughters already and it litterally took us one try for both of them. We were not trying thus time. I would honestly like to wait a year before we try again. Anyways… I started on the April 1, and it happened on April 16. I dont know how long my cycle is normal, but i know it ussally around the same time every month. I took a early show pregnacy test. It was negative, but i cant shake the feeling that i am. what do you think? I wouldnt mind if i was since we are planning on one more child, but i hate not knowing.
Hello Sarah,Good to know that you are positive about whatever the results maybe. So, since you have missed your period, you should take that pregnancy test again after 10 days of missing your period. That is the ideal time when you can get accurate results and get your answers. All the Best!

Pls I have my period on 31 of march and I have sex on 17 of April ,we use withdraw method,my cycle is 29 days,pls am I pregnant because am four days late to my period. Thanks I need answer.
Hi Patience, late period can be because of many reasons. Pregnancy is only one of them. Other reasons may be sudden change of diet or exercise, physical sickness, birth control pills, or even mental stress. If you think pregnancy can be the reason in your case, wait until 10 days after the date of your expected date and take a pregnancy test. This waiting is to ensure the accuracy of pregnancy test kit.
Also, don’t use withdrawal methods, use protection. These methods are not safe. ATB!
Hi my period came on April 2nd my fertile window suppose to be around the 19th there was 31 days in ln last month but only 30 days in April now it’s the first should I be lookung for my cycle to start today or the 2nd or am I pregnant I have been having cramps sleeping alot and nausea but pregnancy test comes back negative
Hello Karen, Looking at your cycle May 3rd is your expected period date. It is too early to think that you could be pregnant since the delay is not too much. Also, To have accurate pregnancy test you should have it 10 days after you skip your period date.The cramps and nausea you are heaving could also be because of worrying or stress. Please relax as taking stress won’t do any good.
I saw my period on the 23 march 2016 until 26 march 2016,then missed my period on the following month april,and saw my period on the 1 may 2016,what does that mean because i never had this kind of pronlem
Hi Olga, please note that periods are not supposed to come every month. They are supposed to come after a particular number of days (21-45 range). After 23rd March, you got your period on 1st May, so it means 39 days. 39 days is not uncommon, so it should not be a problem.
In case you have shorter periods usually, reasons for this delayed period may be sudden change of diet or exercise, physical sickness, birth control pills, or even mental stress.
My ovulation day was on the 13 of April and I had sex on the 12 of April I missed my period but 4days after I started bleeding can I be pregnant please help me

HI Steffy
My husband and I are actively TTC, period last month April was from 14-19, my fertile calendar is from 20-30, and the ovulation date indicate 25th, we had unprotected sex from 23-26, from memory I am in day 7, week 2 (approaching week 3) since my LMP. Wishful thinking that we will get the news we are hoping. What are the chances?
I am also experiencing gurgle and some tightness in my stomach, i remembered day 4 of week 1 (28 April) i noticed a minor red blood stain when I made the stop to the bathroom.
