Good morning, from 15.07 (i.e. already ,15 days) I am late menstruation. So on 29.07 I have passed 2 weeks from the date of the first day of the expected menstruation. I always had regular cycles. Since 24.07 I do pregnancy tests every morning after bedtime, which come out negative. On Monday and Thursday 25.07 and 28.07) I did a beta-HCG blood test, hopefully two will come out with a BETA-HCG (ICD:9: L46) result. I have stomach pain and a temperature of 37.2/37.5 . I do not hide that the situation is quite stressful from the very beginning, i.e. 25.06. Since the time of being late, menstruation is very stressed by the fact that something could have happened. I had frequent intercourse for 4 weeks, each time with protection. During these 4 weeks I slept poorly for a maximum of 5-6 hours, it happened that I ate a small breakfast and then only lunch and dinner at 22. For a year and a half I have been on a caloric deficit, which helped me lose almost 30kg. With weight loss, I have entered a state of anemia, which has been maintained for me for at least a year. Ferritin comes out 12.2. Now I have pain in the abdomen in addition I have in the left side just under the ribs, so I think it's from nerves. I will add that I have lumbar pain, although this has been a chronic problem for me for years. Due to the lack of exercise since June, they happen often. 4 weeks ago I had similar pains and it was before intercourse, and another attack after a week after the start of intercourse, the pain was very strong as if the kidneys hurt and it was the spine helped by analgesic and nose. The feeling of the abdomen is such a pull . I will add that I am 33 years old. For 11 years since the birth of the child I have been sexually inactive,until now
