Ok so I have had car sickness while driving since 2 dpo. My head has felt all wishy washy since about that point as well. Headaches for almost a week straight but they have subsided. My boobs feel a little bigger. Ovulation was around the weekend of the 22nd. Hubby and I dtd early morning on the 24th. Biggest thing I'm noticing right now is my appetite has increased ALOT! eating. A lot. Feeling indigestion. Feeling so full even if I only eat an apple. Constipated and then 2 days later in the bathroom all day. Have a little bit of crampy and had a LOT of water cm. But the thing is everything I've been eating....I just stepped on the scale and I have lost 3 pounds in the last week. No exercise. Just normal daily routine. My question is is increased appetite but weight LOSS a symptom or am I just grabbing at straws. My period is two days late and I have no normal signs of AF showing any time soon. Any thoughts or advice is welcome at this point. Thanks 😁
