The first day of my last period was September 18th 2019 (28 day cycle). I started spotting (pink) on October 8th. My tubes are tied so I didn't think pregnancy, but now I am because I never spot in between periods. I will be following up with my gynecologist. Has anyone else experienced this?

My last period was on the 7th of September 2019. I have been having sex but on the 2nd of October 2019 to 4th October 2019. I have been spotting, but today I'm bleeding and having pains. Could I be pregnant?

My last period was on 20th Aug 2019 and had intercourse on the 1st, 2nd and 3rd of September. Today I noticed some blood stains after going to the bathroom. Can someone tell me the reason behind this?

It could be implantation of the egg.

I had my last period on the 26th of April 2019, I ovulated on the 8th of May 2019. I had intercourse on the 11th of May. On the 17th, I started having brown discharge up to the 22nd. Now it's the 23rd and I'm bleeding. I don't know if am pregnant or not. What do you think?

I have a question. I ovulated on the 4-7-19 and I had bleeding on 4-17-19 when I wiped my self. It was a small amount of pinkish blood. Then the next morning on 4-18-19, I went to the bathroom, and there was a small amount into the toilet. I thought I was having a period so I put a pad on, and there was was no more blood on there. On 4-22-19, I woke up with bad cramps with a little blood like I’m having a period. I need advice because I never experienced this before.

My next period, according to d app is 29th March. but, I saw black spotting on the 27th and red/pink blood on 28th(today). please, is this implantation bleeding or menstruation bleeding?

So I'm pretty sure I ovulated on the 19th according to my app. That's when I did, but my sister's app says my most fertile day was the 22nd. We did the deed on 17th, 18th, 21st, and 23rd. I had symptoms of wetness, cramping, backaches, sort of tired, my boobs didn't hurt, and heartburn. My period is due tomorrow. This morning, I wiped and had pink blood, but not like my normal day before which is brownish. So I'm wondering if its implantation bleeding or AF. My back aches like aunt flow but not as intense.

Ok so... I have a 26-28 day cycle I had my period in Feb 10,2019 and ovulated on day 10,11 or 12 of my cycle. I started having very minor brown spotting in day 20 of my cycle. Now I’m on day 23 of my cycle and I have a bit of cramps but I can not tell if I will be getting my period in the next few days or not. It's driving me nuts and I know it’s too early for an EPT and I will either get my period or not but I can’t take it. I’ve never had any spotting the week prior to my period before. Has anyone had extremely minor brown spotting for a week before estimated period due date and than actually get your period? I’m 37 but I don’t believe I’m in early menopause. My brain is confusing my body and I’m trying to not get my hopes up but I want a baby so badly. We have been trying for a year and a half with no luck already.

I experienced exactly the same as you, period 17 feb, spotting 9 march but according to my app i need to do pt on sunday. so scared...

I'm so confused right now. My last period was Jan 24th. My periods are 29 days . I ovulated Feb 8. I'm suppose to start Feb 22. On Monday the 18th I wiped and I thought I was about to start, it was light pinkish. And on the 19th, same thing happened. Took a test and it was questionable. So I took another one this morning, the 20th. And it's negative. Am I about to start or was that implantation spotting? Everything that I've read said it was. Is it just to early to pick up?

Guest Feb 23, 2019 10:54:57 PM ET

Did you retest?

Guest Feb 24, 2019 12:54:34 PM ET

I am experiencing something similar. i am always regular my lmp was jan 29th and i have a 24 day cycle. i ovulated feb 8th and my cycle was supposed to start friday feb 22nd. but on thursday feb 21st i wiped and tinkled a little blood into the toilet. thought it was my period starting, but i didn't bleed or wipe blood any more that day and had no bleeding or spotting friday the 22nd. on saturday i had a little spotting after a bowel movement then nothing. today i woke up and tinkled a little blood in the toilet and kept wiping until there was no blood on the tissue. took a fr digit and it was negative....

Guest Feb 24, 2019 07:18:33 PM ET

Hi,my last period was on the 02/01/19 and I have a 29 day cycle. My period is due on the 31/01/19 but, on the 29th I saw brown discharge as well on the 30th. But no sign of period blood. Can it be implantation bleeding or just my period about to come soon? My period is always on time and no hints of any discharge from before.
