Hi Doctor, I had periods on Jan 6 and unprotected sex on Jan 30. I got my period (heavy) on Feb 11 which is when my cycle changed from 28 days to 35 days (happening for the 1st time). My next period (heavy) was on March 20 ( after 37 days from last period), but right after this I have swollen breasts, lower abdomen and lower back pain. I have not faced this anytime before. My breasts used to get back to normal size ones I was done with my periods. However, it feels strange this time. Hence, this morning I checked with home pregnancy kit and the result was negative. What could be the reason for 1. Period cycle to change from 28 days to 35 days 2. Pain in lower abdomen and lower back 3. Swollen breast right after periods ( its been 5 days after periods now and there is no pain, my breast just feels fuller) 4. Very mild headache Can I be pregnant even after getting periods in Feb and march Thanks in advance Priya
