I had my last period from 26-30th march. On 31st march, after the bleeding stopped, I went through an intercourse without protection. My partner did not ejaculate inside me, rather he opted for a withdrawal method. After that, I had started bleeding again, but lasted only for 15 mins. During this 15 mins, a huge mass or glob of blood came out of my vagina. I did not take any contraceptives. That's all! on 18th april, I again had intercourse in the same withdrawal method. I was to start my period on 22nd april. Today is 27th april and still there is no sign of period. I had even checked with a home pregnancy test kit at 5am in the morning (i slept at 2am the night before) on 24th and the result was negative. My vagina is secreting slimy substance or mucous at times. I am bloating past 4-5 days, with irregular bowels (which is normal during my periods) nothing else. Please help!
