Pregnancy Info HOME

Hi I need some help. I am totally confused. I came off BC on 16th May 2011. Following that i had a break through bleed, and then my cycle was 33 days long. AF came 19th June lasted 3 days. Me and partner had unprotected s_x prior to my AF and then again on 24th June. 25th June, had spotting once and then nothing. Since we have BD on 30th,1st,4th,7th,8th,10th,14th July. I am not sure when AF is due to arrive as my cycle was always regular on BC but never was before. Since 8th July i have been having cramps like AF is coming, br___ts have been severley aching for a week now with noticable veins that have appeared. I have been really ditzy/confused and peeing alot more, creamy thick CM. Based on a 33 day cycle i ovulated on 8th July and had BD on that date. I am concerned i am PG but unsure when to test, thought i should wait another week which will be when AF is due based on 33 day cycle. Please can you offer any advice?
