On 13th April my partner had her 1st day of her periods and last day was 19 April. On 22 april we had some foreplay and that time I touched my part on her clitoral (no penetration) and that time there was pre cum over my part. She missed her period which was happened to be in may 13 but she is having her period now i.e. On 4th june but it's not like her usual bleeding the flow is not that heavy. 3 months back she had suffered from the same problem of delayed period for about a month. I just want to ask that is there is a chance she is pregnant or not?
