Do you think this is pregnancy or another cyst?
Myself and DH are not trying and not preventing either. My cycles are typically regular 28 day cycles. I’ve never been pregnant before. I am 26 years old.
About 7 or 8 months ago I had what I think was a cyst. It caused me to not have a period for two months. Around the time my missed period was due, I got a lot of PMS symptoms (cramping, some feet swelling) but they fizzled out and never developed into a period. I think the cyst ended up breaking, leading to sudden extremely heavy blood flow that lasted a very short time, then a few days later I got a period that lasted one and off for about 2 or 3 weeks. I had taken HPTs during this time that were all BFNs, so I don’t think I was pregnant then.
My LMP was Jan 26th, making my next AF due last tuesday. She still has not arrived. Since last saturday or so I have: (I starred the symptoms I did not have with the cyst)
experienced on and off light to moderate cramps
My breasts have been achy *
the last couple of days my feet have been a little swollen in the evenings
I keep making poor DH eat out because the food we have in the kitchen (even though I just grocery shopped) repulses me atm *
I’ve been pretty bitchy, I thought I was going to have an emotional nervous breakdown last sunday for basically no good reason at all…*
I normally spot a few days before AF, but there has been no sign of blood whatsoever
I’ve been getting a lot of migranes*
very thirsty, craving water *
felt like I had quite a lot of cm (watery to milky) *
We BD’d a lot during the time I would have been ovulating. I took a dollar HTP Monday afternoon (the day before my period was due). It was negative. I’m planning on testing tomorrow with FMU.
I really don’t think I am pregnant. I’m really afraid this is another cyst.
I’d love to hear opinions, though.

Generally, ovarian cysts are fairly inert, causing no more symptoms than irregular cycles, if that.
The symptoms you had 8 months ago sound very much like a chemical pregnancy where the HCG level never was high enough to be detected by an HPT.
As for this cycle, those could be pregnancy symptoms. Since you are already late for AF, you should get an accurate result on an HPT. Testing sooner than your period is due can give you a false negative.
If you get another negative this cycle, you should see your doctor to find out why your cycles are suddenly off.
Good luck!
