Беременна ли я, если у меня был секс 2 дня назад?

Spotting happe­ns sometimes when e­xpecting. Your missed progeste­rone dose likely trigge­red it. That hormone nurtures the­ pregnancy. Just resume taking it promptly afte­r remembering. Le­t your doctor knows about bleeding too. They may want che­ck-ups or tweaks to ensure things progre­ss smoothly. 

When spotting during your ovulation, this is usually not a matter of concern. But if the bleeding does not stop or worsen, or you feel pain and discomfort then it is recommended to visit your gynecologist. They will be able to diagnose and treat if needed.

You are suffering from side effects after surgery to remove an ovarian tumor. After the surgery, you may feel satiety and want to throw up. This could be because your digestive system is still recovering. Start with small, light meals, and drink enough water. Greasy or heavy foods should be avoided. If this continues, you must inform your surgeon so they can give you proper guidance.
