Do Antibiotics Delay Period or am I pregnant?!

had sex on Feb 6th with a guy I was dating (no longer, which makes this more stressful). He started off without a condom, but then put one on, and he never ejaculated throughout the process. On February 25th, I started on antibiotics (long-term for acne)- brand-name Doryx (doxycycline hyclate). I had my period on February 27th, and it was a normal period as far as I can remember. It's now been 52 days since my last period, and I have no idea what's going on. I'm freaking out! I took a pregnancy test 2 weeks ago and it was negative, and then I took another one 5 days ago, and that one was negative also. My boobs always get sore before my period, and they aren't even sore yet. I keep staring at my stomach because I'm soo scared that I'm pregnant. I've found some sites that show links to antibiotics and delayed periods, but I'm getting nervous because I've never missed a period. I'm typically irregular but only by a week or 2. Never this long. Please help!

Hello,

Welcome to ehealthforum

As explained by you had your normal periods after the last intercourse then chances of pregnancy are not possible.There are various resons of missed periods as stress,hormonal imbalances,drug effect,ovarian or uterine disorder etc.
You require a clinical examination along with USG Pelvis and hormonal analysis to rule out the exact cause of missed periods.Kindly see a Gynaecologist for evaluation.

Take Care!

Hey devkt and dr.agarwal, this is almost the same thing happening with me. I was with a friend on 8th dec and he inserted but not 1 inch deep and he ejaculated outside my body. He later wore a condom and we didn't wait till he came again. On 25th of dec, I had a period that lasted 3 days(but my periods are normally 5days long). I took a preg test after the period and it was negative. On 29th Jan( which was an irregular 35 day cycle) I had my period again which lasted the normal 5 days. I was due to have my period on the 27th of feb. But its 1st march and still no period. What's happening with me????
