Pregnancy?

25-37 day cycle

Ovulated approx. Sept. 14th, had unprotected sex from the 14th-18th at least

Ffw to sept 20th, mild cramps started, thought it was AF, but that's way too early.

Sept 21st had a weird twisting cramp and on off dizziness all day

Sept 22nd diarrhea all day, internal shaky feeling (was not visibly shaking), felt hypoglycemic, ate a lot from this day forward! Took a shower in the evening and got weird bout of chills. Almost flu like symptoms.

23rd dizziness but less severe. Light cramps. Sharp pain in my side the night before. Cramps like AF

24th severe bout of nausea that lasted about an hour or so in the evening.

25th really hungry. Really sleepy. Not a lot of cramping.

26th totally asymptomatic

27th AF due, never came, has been MIA ever since.

Several BFN as recent as this morning, been eating all our food and never feeling satisfied. My cycle is usually 25-33 days but once was 37 days a few months ago. Weird twinges in pelvis and always feels like AF is trying to come but never does. Also can feel discharge dripping (sorry!!) But its always clear and watery sometimes yellow tinged. Going on like 3-4 days late and keep getting BFN, can I still be pregnant and just have super low HCG? It's driving me nuts! I have an OB appt on the 15th of Oct. But I seriously am losing my mind! And don't want to keep eating if I'm not! I don't wanna gain weight if I'm not PG but don't wanna deprive a baby if I am!! Can anyone relate to this? I've never had so many crazy symptoms between O and AF! And since we had unprotected sex for a whole week during O I'm just dying to know!! Sorry for the novel but any helpers!?!?
