Hallow Dear,
Let me answer your queries one by one.
1. In fact there was no risk of pregnancy from the unprotected sex performed just 3 days after the period as it was far away from fertile period. The egg is formed 14 days prior to next period. It has life of 24 hours while sperms are active for 72 hours. Hence a period of about 8-10 days is considered as fertile period. Intercourse during this period has maximum chances of pregnancy. However, your menses being irregular, it is very difficult to locate the day of egg release. (May be you could be having problem in egg release also.) Still, considering your menstrual irregularity, you have taken a wise step in taking
Postinor 2 after the
unprotected intercourse. Postinor 2 is quite effective post coital
emergency contraceptive pill if taken within 72 hours of unprotected sex. You have taken it after 10 hours. So you need not worry about pregnancy. You are well protected.
2. Your irregular menses need to be investigated thoroughly. There are many conditions that lead to menstrual irregularities. Some of them are
Polycystic Ovarian Syndrome,
Thyroid dysfunction, any other reproductory dysfunction, ....... it will fill your complete desk top if I start enumerating all of them. I can guide you on this issue thoroughly if you inform me your age, menstrual pattern, age of menarche (first menstrual appearance), marital or sexual history. You can inform me all this by asking a Direct question. Else, you may report to the Gynaecologist. Irregular menses may result in
infertility due to non-release of eggs. For the time being, you may try cyclical birth control pills for three months for regularization of menses as a preliminary step.
3. Boils around the private parts are usually due to infections; may be sexually transmitted infections like
gonorrhoea, herpes genitalis, etc. You need to report to STI specialist for correct diagnosis and appropriate treatment. You may need antibiotics treatment. Also you will have take care of genital hygiene and be demanding for clean sex only.
I am sure this has given you some direction on your reproductory health problems.
