Brief Answer:
get a serum beta hcg test done...to rule out pregnancy first

Detailed Answer:
Hello,
Thanks for the query to hcm,
tHE CONCERN REGARDING HER PREGNANCY IS WELL UNDERSTOOD. As she is 4 days late for her menses the best way to rule out pregnancy at present would be to undertake a serum beta hcg test. This test if negative or hcg levels less than 1ng/dl shall rule out pregnancy completely.
As you were not protected initially for 5 min, the chances that pre cum also may cause fertilisation and pregnancy and as she was in her fertile period, there could be a possibility.
So the best way to rule out pregnancy as of now is serum beta hcg levels.

Detailed Answer:
Hello,
The normal urine pregnancy test gives reliable results only after 8 days of missed periods and anytime before that the rates of false negatives may be higher.

Hence serum beta hcg test is advised which remains positive 7 days after the last INTERCOURSE or SEX. This is a blood based test and a small 5ml sample is taken for the lab test.

Detailed Answer:
Hello,
Increased mucoid discharge is not exactly the sign of impending menses, rather the premenstrual symptoms are usually in form of mild pain in lower abdomen, nausea, headache, mood swings, increased frequency of urine abdominal cramps.
If you want you may wait for another 4 days and then you can do the urine pregnancy test if you desire and till then there are chances that the menses may start as well, so you may either wait or if anxious then you can get the serum beta hcg test for results.

Can just one antibiotic pill delay menses that much?
doctor
Answered by Dr. Sameer Kumar (8 minutes later)
Brief Answer:
answered

Detailed Answer:
No it is unlikely that a single dose shall delay the menses, but the concern is not antibiotic but the reason or illness why she was given an antibiotic. ILLNESS during menstrual cycle can cause stress in women and stress can easily delay her menses by a week or so.
So you may wait if you desire.
