So i ovulated late last month around the 14/15th september. We had sex on.the 16th, so theres a possibility we could have concieved if i ovulated on the 15th. I got a very short and light AF on the 29th which fits in with when i think i ovulated. I never get any pms symptoms and since my period finished on the 31st i have had sore tingling boobs and now on cycle day 5 and 6 have had nausea which is very unexpected. Ive done multiple tests all of which have been negative. What would be causing these symptoms? Is it normal to have pms symptoms after AF? I have a doctors appointment (mostly for the nausea) but i dont even know if i should go...I feel silly.
