Conception Ambiguities

Hi, I am 31 years old and all my life I have had normal cycles and they would generally come on time. But in May 2012 I was 10 days late for my cycle and I took a pregnancy test which came back negative. Every since my cycle in May it seems like my cycle is always late. Is this because Im getting older that my body is changing?

so, my husband and I arent trying, but not really preventing either, just kinda see what happens. Anyway, I have been on BC for 10 years straight except for the last 10 months. This is the first time in my life I am late, I am now a month late and still no period and still Negative pregnancy tests. My husband has been working out of town so if i was pregnant I would be 8 weeks already. I was sick with a sore throat the month i missed my period. Anyway, what i need to know is, could i be this far along and be getting negatives (i know theres a chance, but how likely?) , and if i skipped cause i was sick when should i expect my next period? back on my normal sched? because if so that would be today-couple days and no cramping so far. I have insurance but havent met my deductible, so when should i go see a dr. instead of waiting it out because unless im pregnant or a serious problem, id rather forego the dr. ...any help would be great! ( p.s.. this would be my first so i dont know what "feeling" pregnant would be like)

I've had regular cycles my whole life. Now I'm thirty and have been trying to conceive for the past 7 months. Three times since starting my period has been 1 to 1 1/2 weeks late. Each time I'm convinced that I'm pregnant, but no! I've also seen spotting for the first time in my life so my worry is that we're conceiving but that it doesn't "take." Has anyone else experienced this?

My fiance and I went off BC about a month ago. We had some fun on CD 8 and 13. I had a slight moment of panic and re-started my BC on CD 16. According to my original cycle, I'm on CD 38- 2 days late.

Is it possible I'm pregnant?? Or psyching myself out...

So, this is weird. I was on the pill which shrunk my 33 day cycle down to the 28 day, got off of it because of side effects a few months ago, and had a period 28 days after that (CD 1 being former CD28). I had a bit of light red-brown discharge a 2 wks or so ago (splotchy memory). I was feeling grouchy and fatigued, so I checked the site to see what my CD was this month and it was 26- so I figured PMS and took primrose and that was it. But there were very light cramps for only about 10 minutes 1 day, and then a heavy cm since then. It's now CD35 and started having nausea yesterday. I've been pregnant before, and they didn't show until my 2nd missed period (which resulted in a MC for my 3rd since we didn't know really. I just thought it was irregular due to my IUD being removed.) Sorry, got distracted. Anyway, I'm just curious: will a blood test tell me if a HPT doesn't? I'm due for a tubal ligation on the 27th! That would be some funny stuff if I was pregnant again....
And another thing is, my nut allergy that I developed with a previous pregnancy disappeared, and I'm CRAVING peanut butter! WEIRD! Though it may just be a coincidence. (mind you, I couldn't even breathe near someone eating peanuts a month ago without feeling like I had inhaled chili powder.)

I'm in the same situation. My period is irregular but has been coming like clockwork for last few months except this one. It seems to have take a 5 day hiatus. I did test on the second day that I was late but didn't use morning urine and got a negative reading. On the flip side I'm feeling lightheaded, nauseas, stomach discomfort, bloated beyond belief, and of course still late. I'm going to wait until next week or so to test again preferably at the doctor so if it is indeed negative I can get something to bring my period on. In the meantime, I guess I'll keep my fingers crossed.
