How will you know weather you are ovulating or not when you are not seeing any thing like drawing fluid
Hello Jacinta, generally no fluid happens just after ovulation. You can focus on other signs of ovulation- like many women feel twinge of pain or cramps in lower abdominal area (usually on one side only), Also, you can try using an ovulation predictor kit. Good luck!
Ok my last period was August 26 to august 31. I was supposed to get my period September 23 or 24. I had unprotected sex on the 10 of September with my bf then we broke up. Then I was with my ex September 18 and then I went back to my bf on the 20. I got what I thought was a period on I think the 13 14 15 of September but it wasnt a period. I’m a little confused about the father who can it be smh.
Erica, are you sure you are pregnant? Have you done any tests for it?
Comment Text*i had my period on 7 of March and I had sex on 18and 19 I my pregnant
Hi Jessica, have you missed your period in March? Or have you been experiencing any signs or changes in your body?
Comment Text* i had my last period on 29 February and ended on march 4, another one came this morning of which it should come on 25 of march and have 26days mensural cycle. Any help
Hi Alice, it’s perfectly normal for period to come early/late by 2-5 days. No worries.
I got my period march 22 (yesterday) I’m wanting to know if I will be back on it @the same day next month. I usually get it every 21 days and it lasts 5 days at the most but lately it comes early. I’m not sure how I’m supposed to calculate in between.
Hi MiraN, if you get your period every 21 days, then it is the number of days in your cycle. By that info., you should have your next period after 21 days to 22nd March, so it should be on 10th-12th April.
I had my period on 2nd March 2016 and had sex with my husband on the 22nd of March. Is there a chance of me getting pregnant?
Hi
I started my period 18th February. finished on the 24th. my estimated fertile window was 1st-5th March. when i wass estimated to ovulate i experienced light spotting for 2 days. My next period was due 17th Of this month and hasnt come yet. ive had sore breasts but no period pain. Could i be pregnant? im just unsure as i came off depo 1 year ago and been trying for 6 months now
Hello, sore breasts may be due to many reasons but as you are missing periods as well, I would suggest taking a pregnancy test. All the best!
I had a miscarriage on the 24th of last month and since then have been having sex with my guy but have not seen my period since. Am I pregnant? I’m not getting it.
my last period was feb 11 2016. i had unprotected sex on feb 21 , 25 , 28 march 19 and 21.
i didn’t get my period on the 10th.
Hi i had may period last feb 23. And supposed to be my period today. But we do it inside today. Is that safe?? Thanks
No it’s not. You should use protection if you don’t want to get pregnant.
hello i feel like i dont have a fix cycle sometimes its 28 days sometimes 30 days how can i know when I am ovulating ??? im trying to use some ovulation test at home but i dont know how much can be exact .. thank you
Hi Wafa, there are many ways to calculate ovulation. First, try charting your number of days in the period cycle. After a few months, you may notice a pattern.
Second, Cervical mucus- As you approach ovulation, the cervical mucus becomes plentiful, slippery, clear, and stretchy.
Try the ovulation test and see if you get more clarity. All the best!
Good morning, I saw my first period on the 22 of February 2016, that’s was my first period after not using a depo and my first period was normal. I was supposed to see my period on the 21st of March but I didn’t and I haven’t made love since my period.What does that mean? Or is it that my cycle is not 28 days?
My last period was 30th June to July 4 I had sex with my fiance on 15 16 17 and before 30th am already feeling weak and brest swallowing before I met my ex boy friend on 28 of July we had sex and I did pregnancy test 1st of August and went for scan 14 august am already 7weeks pregnant. Please tell me who’s the owner of the child
Hello, if you mean that you were 7 weeks pregnant on 14th Aug, the implantation should have been on 25th-29th June.
Hi , I had ovulation spotting which was one light pink spot on 10/3/16 (cd21) and my fertile days was 5th to the 10th of March , my cycles are 32 days and now no period when shall I test . Thank you
Hi Emma, when were your last period (in Feb)?
Hi I did two tests they were positive and my last period was 19/02/16 but not sure how far I am x
So I had my period on the 27th of February and it finished the 3rd or the 4th of March, the calendar says it supposed to come the 26 or the 27 of March and I have it the 22nd of march and I’m confused. The length of my cycle is 28 days.
It is normal for a cycle to change between periods. A period can come before or after it is due without it being a cause for concern.
I’m 36 years old, I have a 24-day cycle…Feb 27 – Mar. 2. My cycle started with spotting on the 3rd…normally week long. I has unprotected sex on the 7th…not sure about ovulation but lighter period I’m assuming on the 16th. But wasn’t expecting to see at until the 22nd.
Hi steffy, my friend had her period last feb 20 and had sex with my bestfriend on feb 29, she havent got her period yet but had this cramps like dysmenorrhea type. She was expecting it either march 19 or if ever march 25 but still her period didnt show up. She’s really worried we just graduated from college and her mom would die if shes pregnant.
Hi Joyce,
The cramps may be due to many reasons including pregnancy. The best way to know is using a test. Anyway, I hope your friend has gotten her period by now and doesn’t need the test. All the best for her!
Also, it’s never safe to have unprotected sex, not even during period. Always use protection.
Hey. My period ends on the 5th day, is it possible to ovulate on the 6th day? Because I saw something like gum in my private part but not too white. So can I conceive if I have sex on the 10th day?
