We had protected intercourse (condom) on 4th this month. On 5th i had my periods. This time, the cycle was of 28 days instead of 32. My periods lasted for 5 days, but lighter than usual. Infact there was nothing on 4th day and very slight pink spotting on 5th day. Today on 22nd, i am feeling slightly nauseated, quite fatigued, increased sleep, body aches. Just replicating my pregnancy symptoms during the first three months last time i was pregnant, though on a lower scale. It has been two days. Though unlikely, is there still a possibility that i could be expecting? Apart from pregnancy what else can be the reason? it is somewhat affecting my chores.
