Menstrual Cycle Day 27


What is happening internally?

The corpus luteum continues to release high amounts of progesterone to maintain the uterine lining. The zygote (fertilized egg) is increasing in size and growing larger every day. The amounts of hCG are increasing, and may be high enough to result in a positive pregnancy test. If conception did not occur, the amount of progesterone being released begins to drop due to the corpus luteum dying. The lining may begin to slough off.

Outward symptoms:

Basal body temperatures remain high above the coverline and may even steadily rise higher. Cervix may be low, firm and closed, or slightly raised and softer. Cervical fluid is dry or it may become creamy. You may experience bloating or water retention. You may experience a headache. You may have to urinate frequently and may or may not experience food cravings/aversions and fatigue. If conception did not occur your basal body temperature may be dropping down due to the corpus luteum dying. Cervical fluid may be creamy to watery. You may have water retention, headache, moodiness, spotting and cramps.

I started bleeding today, but it was quite dry and brown blood light all day. then it got a bit heavier and redder but less than a normal period. i wondered if it was an implantation bleed, or if it's was just a chemical pregnancy. my emotions are all over the place. has any one else experienced the same thing?

Hi meeee, i had two ectopics 2005 n 2006, wasn't planning on it, it just happened, sometimes when we keep dwelling on it and it becomes an active chore, than it wont happen, i would try to stop trying to become pregnant, have intercourse without making it a baby issue. keep your mind off of it, and then it will happen in gods time not yours. trust me on this!

Iv been trying 3 years - im now 24 - had 1 positive in aug 2011 and lost it sept 2011 - nothign since :(

AKrum Jan 25, 2013 08:08:38 PM ET

It's happens. you really have to chart and test for you to be 100% sure when you're able to conceive. it's such a tricky thing. i've been trying for over a yr now and the only thing i've come out with is 2 miscarriages and a d&e procedure. you're not alone. i feel frustrated and i don't know when it'll happe . if nothing in the next couple months id ask the dr. to help you. hope this helps. sorry for your loss :(.

cleothessa Sep 26, 2013 10:44:05 PM ET
