I recently checked my most fertile time using an online calender and it stated that my most fertile time was between the 18th april - 23rd april I have a 29-30 day cycle and my last period was on the 7th but I was only on for 2 days so my period stopped on the 9th, I had intercourse on the 9th and I think thats why I stopped bleeding?

but then my fertile time came up and I had intercourse 6 times in 4 days which was in the fertile window, if the online calender was right I was have ovulated on the 22nd or 23rd and I did feel small craps so I think this was ovulation if this is true then its only been nearly 8 days after ovulation, Im having small craps in my lower stomac, I've felt sick for the past 4 days, My eating has changed as normally I can finish my dinner but end up eating small amounts otherwise I feel sick. I keep feeling tired but once im awake I cant go back to sleep, but I end up sleeping for about 15-16 hours.
Also the little bumps around my nipples are more noticeable then usual and my sister even told me that my breats look bigger, they also look darker than normal.
Also my gums seem sore and I taste blood a lot and have done for about 4 days

I have not missed my period yet and it is due on the 5th-6th may, I went to see a family planning doctor who told me there is 30% chance that I could be having a baby.
Im not sure what to think one day I think I am and then another day I dont and I dont know if im getting confused like because I want to be pregnant that these symptoms are just happining because I want it to?

I know that I should do a test and I was going to wait until the 2nd as I have 2 pregnancy tests waiting but dnt want to do it to early to get a false negative or visa versa.... please any info on this
