I had sex for the first time with my boyfriend last week right after I got off of my period and we used a condom but it hurt so bad I told him I had to stop so he didn't finish. But I'm worried I may be pregnant because of what I've been reading online. Also my period is irregular so I have no idea when I am going to get it again.
Hi, the chances of pregnancy would be literally zero even with a regular cycle as the egg won't be released untill 14 days into the new cycle from the start date of your period,the average cycle length from start of a period to the start of the next is 28 days as it's roughly at 14 days when the egg is released meaning the fertile window would be between day 9 to around day 16 because once the egg reaches the uterus if it doesn't get fertilized it gets expelled when the period starts. Sperm can only survive for 5 days inside the vagina then it dies, so all in all I think you have nothing to worry about. You did the right thing by using protection too, to help make intercourse easier try to stay relaxed, make sure you have a lot of foreplay first so your vagina is wet an also get some water based lubricant to put around the vagina entrance and inside with a finger and over the confom too and by doing that you should find his penis slides in easier and causes less pain.
