I'm 28 years old. My period had been very regular (same day every month and lasted for 7 days) since I got married and had 1 miscarriage my period started to mess up, now is one week late every month for about 3-4 months, then this month I got my period 2 days before my period is due, is was quite heavy 2 times that day then spotting for the next 5 days (which my period only last 3 days then spotting for 2 days the last 3-4 months) I took a pregnancy test couple day ago and it came out negative. Have anyone had this experience before and end up to be pregnant and yes I did had sex on my ovulation days (I use the ovulation kits).
