Cycle Perplexities

I was convinced I was pregnant last week and was super surprised the test came up negative.
I know, I need to go buy another pregnancy test. I'm nursing my 15 month old about 7 or 8 times in 24 hrs. I've had 3 periods so far post partum. I normally have kind of long cycles, average 37 days, but 40 days? Now I'm at day 45 actually and still no period. Is it possible to go back into lactational amenhorrhea again? I guess I'm probably pregnant. That would be OK, but a little earlier than planned.

seems like the only place to put this. Back in late febuary i strained my lumbo sacral area of my back. never had back pain before or during my period, but ever since ive had extreme low low back pain for like a week and a half before dreaded af comes. Im getting rather tired of eating tylenol or other pain relievers the entire time.

I'm ttc for the first time. I just went off of bc in July. I had a normal 30 day cycle. It's now my second cycle after coming off the pill, and I'm on CD 43! I have been a little stressed and my schedule has been a little different, but even before I went on the pill my cycle was always very regular. I took a hpt on CD 35 and 40 and got a BFN. I don't think I'm pregnant this time around, but when should I be concerned if af still hasn't shown up?

hi there..i am 33 yrs old with a almost 5yr old girl. my periods have always been normal until i had a baby and they have been normal but then change but for the most part normal. for instance since july my cycle has been wacked. i had 2 periods in the month of july with spotting in between. than i went to gyno and she did a ultrasound vaginally 2 see if uterus was ok, ovaries everything came out great. she told me to wait to see if august cycle would normalize since this only happened once. well on aug12 at night i bleed with a clot than aug 13 nothing all morning until night time before i went to bed it was the same thing than aug 14 was the real period i was excited but i lasted until aug 21 the brown spotting began..so i have been spotting brown very very little...today i had very light brownish pink but ever since period finished i have been cramping like gonna get period. my sister says it is because i had such a heavy and long period. i have never taken BC and i do want to have another baby well we want to try but can i still get pregnant if cycle is like this?so has anyone had this before?

I have a question.......Every month I can tell I have ovulated because one to two days after my breasts hurt like crazy. They continue hurting until my period starts or one to two days before my period starts. This month I am 6 days past when I should have ovulated and my breast are normal. Nothing hurts. What could be causing this?

OK so I have 2 daughters already..husband and I have been ttc the past couple of months. Of course when we decided to start ttc my periods decided to start coming earlier or later than when they were expected.

I'm expecting my period next week, yesterday I wake up from a nap..have some very light brown blood when I wiped..figured okay period is just a week before I expected nothing unusual in that lately.

Now normally my period will start with light brown or pink and progressively get heavier that first day. Yesterday when I took the first tampon out..there was some of the brown coloured blood..not a lot and no where near how much it usually would have been. Didn't think anything of it just figured I caught it really early this time.
The next time (this was about 6-7 hours later) there was very slight pink on the tip that was it..figured it was just slow getting started..this morning again there was hardly anything but back to the brown colour.
Again this afternoon barely anything and it was more of a slightly coloured discharge.
Now with my daughters I never had implantation bleeding so I have no idea if this is what it could be or if it's just my period being wacky again..because the "bleeding" seems to have stopped.
